10 Great Movies With Terrible CGI

10. Deep Blue Sea

In Deep Blue Sea, a group of marine explorers battle a school of super-intelligent sharks. Based on that storyline alone, you'd assume this will be a dumb B-movie in the same vein as Birdemic or Maximum Overdrive.

Even though Deep Blue Sea could've been trashy schlock, it's elevated by an excellent cast, including Samuel L. Jackson, LL Cool J, Stellan Skarsgard, and Thomas Jane. On top of that, it has some genuinely great jump-scares, including when Skarsgard's character gets his arm ripped off by a Great White.

But let's not forget what Deep Blue Sea is best remembered for. After Jackson's character gives an uplifting monologue, a shark comes out of nowhere and rips him to pieces. Because you genuinely don't see it coming, this moment is regarded as one of the best jump-scares in cinema.

That's why it's ironic how the film's defining moment happens to have the worst special effect. Not only does the computer-generated shark look like its composed of rubber, Jackson's CG counterpart looks hilariously unfinished and contorts its limbs like a rag doll rather than a human being.
