Lack of good storyline.

Although I seem to have had higher expectations than I thought, the movie is super entertaining.

I didn’t really have many expectations going into the movie (good or bad), but I actually really enjoyed it. I really liked the characters and the banter between them.

There are moments in this movie where the great movie it could've been peek out... They're fleeting, here, but they're worth savoring, and they happen often enough to make it worth your while.

The premise of this movie had a lot of potential, but it didn't meet my expectations.The characters were either completely forgettable or annoying. Some of them died because of their stupid decisions as if the characters only existed to embody negative character traits. For example, two characters started fighting each other while being surrounded by aliens. Another character went crazy from fear and messed up the lights that were keeping the characters safe. I didn't feel scared at all, because I didn't care about what happened to the characters.In fact, I kept hoping someone would kill Riddick, because he was so unlikable. I feel like I'm missing an inside joke, because there are so many reviews praising him. He crashed the ship, killing most of the people on board. His lines were cheesy and edgy, his glasses looked silly, and his night-vision made him an obvious plot device. Even at the end he was still playing mind games with the female lead (whose name I forgot) and wanted to abandon the other survivors, showing that he hadn't got redeemed at all. The worst part is that his casual attitude made me feel like he was never in any danger. He was a male Mary Sue who had the plot revolving around him. Characters in horror movies shouldn't seem invulnerable.Also the planet didn't make any sense. Why would the dominant species on a planet that experiences constant day be scared of daylight? The planet didn't get enough eclipses to let the aliens come to the surface to hunt regularly. If they hunted all other species to extinction, what were they eating between the crash-landings? Each other? Then their population should be shrinking and not be so massive. The problem could have been fixed by giving the planet extremely long days followed by extremely long nights, like some real planets have.

It's hard to find new stories in sci-fi genera. Most of the movies just circles around some basic themes. This movie is a breath of freshness in this genera. Although there is a spaceship in this with a not so unique fate assigned to it at the beginning but the plot changes its course to some uncharted territory pretty fast after that.The making and acting is decent. The interesting story creates a thrilling experience throughout its runt-time. Vin Disel nails his part with perfection. It was more than impressive to watch him act.There are some unnecessary events in the story that felt forced to me. These were avoidable and probably were there just to get the audience emotional(if you have seen this you might understand what I am talking about). Without these I would've probably considered this to be a perfect sci-fi classic.

Vin Diesel's best movie past and present, no refutation required. He is not a great actor but this movie was his to own and he did. All the actors did their parts to perfection, but this was a diesel powered vehicle.ANY person who gave this less than 7 out 10, truly does not understand great movie-making and should be ignored. They do not understand the subtleties of the script and direction, or the nuances of acting. It builds, it teases, then it executes. In my estimation it was more worthy of an Oscar than Babel and so many other worthless and forgotten titles. Seriously, I can't remember any others and I can only remember Babel because it was so boring and bad, and I watched it, which is time I cannot get back.This movie only has one flaw that I will not mention, because lefties will have a fit, but other than that, enjoy and appreciate this fine film.

The most difficult part of writing a review of this contrived and poorly acted film is trying to squeeze ten lines into this posting from a film so totally lacking in substance. Radha Mitchell is a very talented and stunningly beautiful actress ( check out " Everything Put Together " ), but the cast of characters and twisted ( perhaps even shopworn ) escape from the jaws of whatever plot line left me repeating " not again.... " . As might be expected when creativity falls short in developing a new ( and potentially interesting ) idea , an extremely long night as one planet eclipses another , the producers/writers resort to conflicts and weaknesses among the cast of characters to provide some substance . It doesn't work , and there's nothing you haven't seen before . Mitchell has been used all too often to provide eye candy for an attention grabbing title with little substance , much as Carol Baker during the '60s and '70s . She deserves better.....WOW ! I stretched it to 15 !
