everything you have heard about this movie is true.

Fanciful, disturbing, and wildly original, it announces the arrival of a fresh, bold voice in American cinema.

While it doesn't offer any answers, it both thrills and makes you think.

It’s fine. It's literally the definition of a fine movie. You’ve seen it before, you know every beat and outcome before the characters even do. Only question is how much escapism you’re looking for.

Why?! That's the first thing that springs to mind when watching this pile of rubbish. Why do we have a guy pretending to be chased and attacked and interacting with sub par CGI creatures from millions of years ago?! It's almost like the subject matter wasn't interesting enough to the producers so they tried to make it more exciting and like a blockbuster movie. This is made for morons. If you have any interest in Dinosaurs or pre-historic creatures in general then go on youtube and check out some actual documentaries that give you information about these amazing creatures. If you like movies like sharknado....then you might enjoy this. Utter, utter none-sense. If you enjoyed this...you are an idiot.

This doc is atmospheric, interesting, and covers a lot of ground. The CGI is simple but effective. There is one very memorable scene with enormous reptiles (Liopleurodons) feeding on an 80-foot fish (Leedsichthys) in underwater near-darkness... epic for sure... and there are some other great moments.The host, Nigel, does his job well. This 3-episode series takes the approach of transporting the narrator through time to actually swim alongside the creatures he's reporting on. The script of his exploits to this end is... okay. It's somewhat weak a lot of the time ... but the topic is engaging enough to balance it out.Overall, a solid 7/10, maybe even higher. Worth a watch!

The most notable difference between the Chased By... series and its Walking With... predecessor is the addition of a live narrator and guide, zoologist Nigel Marven. This show would have scored a lot higher without this addition. Treating it like there was actually a guy interacting with the ancient creatures as in a regular nature documentary was off putting. Nigel Marven does a good job at mimicking these interactions but suspension of disbelief is something which should not be needed to enjoy a factual educational series. This spin off series is known in the US as the 'Chased By' series and in seeking to make the show more engaging it has caused the series to jump the megalodon by trying to inject cheap Crocodile- Hunter style action and theme-park thrills, rather than maintaining the scholarly objectivity of Walking With Dinosaurs' invisible narrator.Some people will enjoy this series a lot and it could inspire some children to get into the field but I worry that the gimmick makes it harder to retain any of the information.

I really liked this 'documentary.' I saw it on animal Planet a couple nights ago, and I must admit it was very fun! The 'movie' stars Nigel Marvin, who goes exploring in the seven most dangerous and ancient seas. We start off with mere sea scorpions and go up to Megalodons! The movie plays itself as if the monsters were real and an actual threat to the host. Another interesting thing in the movie was that the host walked around and interacted with the animals as if he were Steve Irwin or Jeff Corwin.I actually thought it was thrilling and educational at the same time! If you watch Animal Planet on a regular basis, watch "Chased By Sea Monsters." 8/10
