The plot isn't so bad, but the pace of storytelling is too slow which makes people bored. Certain moments are so obvious and unnecessary for the main plot. I would've fast-forwarded those moments if it was an online streaming. The ending looks like implying a sequel, not sure if this movie will get one

It's a movie as timely as it is provocative and amazingly, for much of its running time, it is weirdly funny.

The film may be flawed, but its message is not.

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

After the events at Lake Victoria, the pre-historic school of blood- thirsty piranhas make their way into a newly opened waterpark. To be honest i think that the first Piranha film was alright but this? It was retarded and not even in a good way. The film is full of over the top kills that don't even happen by the Piranhas themselves, there's even a scene where a Piranha is stuck inside the @ss of one of the characters, another one has legs and kills a child and a lot i mean a lot of 3D shots of fake big tits running around and screaming. The acting is complete garbage from most of the cast especially David Hasselhoff although some of them do try like The Flash's Danielle Panabaker or even Matt Bush and Christopher Lloyd also the cgi is awful and the overall product of this "film" is a waste of talent, time and money. (0/10)

I'll start by reiterating that Piranha 3DD is complete trash and not worth the price of admission or a waste of a free ticket, but having said that I must say that if you catch this on TV one night or get a copy from somewhere, this piece of schlock is a hoot.The whole premise of the movie, if you can look past the bad science and implausible plot lines, is that the piranhas have moved from Lake Victoria via subterranean rivers and set their sites on a water theme park. What sets this park aside from any others I've ever been to is the adult area, complete with the total nudity, droves of splash-happy double-D women and underwater cams. As well as the horny pool boy who likes to have sex with the underwater wall jets.Just as Richard Dreyfuss was the throwaway token star in the first Piranha remake, we now have Gary Busey, who really just seems to be playing himself. He and a friend wade out into a lake to retrieve a dead cow and it appears that the body is infested with piranha eggs and newly hatched piranha. After they are dispatched, the ravenous prehistoric fish kill a young couple after their van rolls into the lake. A few more random incidents occur and after a small piranha swims up inside a girl while skinny-dipping and then, ahem, latches itself onto a guy during sex, which results in him cutting the fish off by slicing off part of himself. (I'm not sure why he didn't just stab the fish so it lets go, but as I said earlier, it's complete trash and everyone is meant to be completely stupid). It's now apparent that the piranha are on the move again.A quick visit to Christopher Lloyd, who's now a YouTube sensation, and the gang are on the look out for piranha getting into the pipes. As usual the owner is having none of it and thanks to a crooked cop, any thought of shutting the park down is dismissed, so of course all hell breaks loose and fun slides run red as human is back on the piranha menu.David Hasselhoff is the guest celebrity, playing himself, playing his character from Bay Watch who is there to help open the park. He's basically made for this type of film as he's no actor, and as a comic relief is perfect for the tone of this flick.Ving Rhames also makes a comeback in this, now as a wheelchair bound aquaphobic. However when people start being eaten all around him, a pair of detachable titanium legs, complete with shotgun attachment, helps him overcome his fear in the best way possible.Really this is a junk film that turns out to be a lot of fun, which is pretty much like every other piranha film ever. The only difference in this is that there's a hell of a lot more nudity and more ridiculous, unrealistic death scenes than you can poke a severed penis at. Lots of half naked buxom women covered in fake blood running around mindlessly for the sheer sake of running around and the ending leaves us with the notion that this piranha franchise is going nowhere fast. I gave it a 5 as this did at least give me a few good laughs.

When I saw the cool, gruesome and refreshing monster-movie "Feast" for the first time back in 2005, I immediately thought that this unknown director John Gulager could perhaps be a talented addition to my precious and favorite horror genre that so desperately needed new blood. When I then watched the two inferior sequels my enthusiasm got tempered quite a bit already, and after seeing "Piranha 3DD" I'm entirely convinced that he's just another stereotypical dumb and low-keyed director who abuses the genre in order to serve idiotic plots, horrible computerized gore effects and infantile gratuitous nudity… "Piranha 3DD" features everything that gives horror – as well as sequels in general – a bad reputation. It is clearly put together too hastily, meaning that the production got green-lighted before there even was a plot in order to cash in on the success of Alexandre Aja original/remake, and strictly aimed at audiences who presume that horror is all about big-breasted bikini girls and ridiculously oversized creatures designed with computer programs. My God, I just feel so old and whiny when I'm writing this down… Obviously I wasn't expecting this movie to become the next "Psycho" or "Rosemary's Baby", but I guess I really was hoping for a tad bit more creativity, charm and respect for the source material. The creature-features from the 1970's were also far from perfect (like "Grizzly, "Squirm" or even Joe Dante's original "Piranha") but at least they were filmed with a lot of dedication and inventiveness. Yep, here I am sounding old and whiny again… What keeps surprising me about these nowadays horror flicks is how the director manages to convince terrific actors to lose their dignity! Christopher Lloyd and Ving Rhames stepped out of Aja's original with a relatively unharmed reputation, but here they simply ridicule themselves. And Gary Busey apparently needed some extra money as well. The same can't be said for David Hasselhoff, as he somehow succeeds in fitting this dud of a film right into his already downwards spiral career. He actually spoofs himself successfully by appearing as washed up TV hero typecast as the Baywatch lifeguard and mumbling things that are so true; like "Welcome to rock-bottom". Anyways, in case you give a damn: one year after the bloodbath in Lake Victoria, the sleazy businessman Chet counts down the days to open his luxurious and flamboyant water theme park with a very peculiar (and not at all sexist…) gimmick, namely double-d swims for free! He has even foreseen topless adult pools and installed underwater cameras, much to the frustration of his righteous stepdaughter Maddy (who only has a B- cup). But naturally Chet is a corrupt scumbag and his illegal installations pump up the water from underground Arizonan lakes. Those lakes are infested with prehistoric piranhas, a little detail that Chet and his corrupt buddies actually should know considering the Lake Victoria incident, and a couple of mere hours after the grand opening the hideous razor-teethed fish are munching themselves a way through silicone breasts. The highlights of "Piranha 3DD" include a fairly atmospheric opening with images of the forsaken Lake Victoria and an awkwardly uncomfortable moment involving a fish preventing a young couple from losing their virginity in a romantic way. The gore is stupidly over-the-top and the piranhas don't come across as menacing whatsoever. If you ask me this is pathetic nonsense, but hey, I'm old and whiny

First off, I didn't think the first one was great either (but 3 1/2 stars, sure.) but this one's got nothing on #1's plot. The tension, and I guess a scare or two, but there is no ending set piece complete the film. The first one had the kids stranded and whats-her-name trapped in the boat. This film has none of that. The filmmakers understand the b-style, but when your monsters stay under the water for the most part, your people should be stuck in the water! The climax should have had someone trapped- like maybe on one of those water park lifeguard islands, like the ones in the middle of the pool, when you see the film you'll understand how that would work well! But for some reason: No. Other than that there are some great celeb cameos, humor and action to pass the time, but I guess that's not what people were expecting from this film. It's not bad though. I laughed, and had some fun- so I'm thinking the crazy low rating (3.8?? That's lower than those Syfy channel movies!) is because Piranha 3DD is goofy, not scary, and such a change in mood, story, and humor. People where expecting Piranha 2, they got scary movie 6. And apparently nobody wanted them to go comedy. And in some ways comedy doesn't work for this film, e.i. the first film wanted you to be impressed/entertained by the effects and the scares, and these type of comedy are basically making fun of them selves, so the film doesn't let you admire it's talent. Piranha 3DD is fun, and deserves much better than what it's gotten, but goes to show that spoofs and horror flicks don't mix well.P.S. This film actually did okay over seas, and some of the behind-the-camera crew are interested, so I'm keeping my fingers crossed for Piranha: Part 3D (The third Piranha movie- hoping it might happen!)
