10 Horror Movies With The Worst CGI

Good horror is all about presentation.

Even the scariest screenplay will fall flat with audiences if it lacks in its execution, and for horror, that's all about looks.

Sure, there's more to be afraid of in what we aren't shown, but once we do finally catch a glimpse of whatever evil, supernatural or otherwise malevolent force has been sending shivers down our spine, it had better be damn believable.

Horror as a genre leans so heavily in forcing us to confront the things we can't explain, and in doing so, it sets itself a rather unique challenge: making the unbelievable believable.

When this is done right, it's terrifying. Through the use of good acting, practical effects and clever cinematography, we've seen so many ghosts, ghouls and splatterings of gore over the years that the horror audience has almost become immune to the gut-wrenching terror that these movies once inspired, but for every movie that pulls off those scares, there's another that simply doesn't.

The extensive use of CGI in horror movies is something that almost always dates the title tremendously, but the following entries go beyond that.

These are 10 times that horror movie CGI was the absolute worst.

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.
