10 Horror Movies With The Worst CGI

10. Freddy Vs. Jason

While neither the Friday the 13th series or the Nightmare on Elm Street series have ever leaned too heavily on CGI - in fact, the latter is known for its extensive and impressive use of practical effects - there was one particular movie in which the visual effects used were notably bad.

In Freddy vs. Jason, a crossover title in which (you guessed it) Freddy Krueger and Jason Voorhees are pitted against one another, there is one scene in particular that boasts some truly laughable CGI.

When the standard slasher-movie stoner character Freeburg begins partaking in his favourite pastime, a giant CGI caterpillaresque creature appears complete with its own paraphernalia. It promptly blows smoke in Freeburg's face before luring him into a morgue and possessing him, revealing itself as none other than dreamworld murderer Freddy Krueger.

Not only is the lifting of an Alice in Wonderland character a bizarre concept for this slasher movie, but the CGI is utterly unconvincing, and the two come together in a perfect storm that makes this scene more likely to produce laughs than screams from its audience.
