12. The Anacondas
Movie: Anaconda 3 (2008)
It's not that Anaconda and its sequel, Anacondas: The Hunt for the Blood Orchid, sport excellent visual effects in comparison to 2008's made-for-TV follow-up Anaconda 3—the reason why this David Hasselhoff-starring installment earns a place on this countdown is that its filmmakers adhered to the old horror movie philosophy that sequels need to amplify the showiness.
So as Anaconda 3 stumbles to the finish line over 91 hilariously dire minutes, the humongous snakes receive tons of screen time, calling more and more attention to their poorly rendered "realness." Anytime the creatures move, Anaconda 3 feels like a glossier, modernized version of Snafu.
