Despite the approval of the professional critics, the film suffered from outspoken negative word-of-mouth from the internet message board community, many members of which are attempting to claim credit for "sinking" the film. Among the complaints voiced by genre fans were the film's similarity to Night of the Creeps, as well as their personal dislike for the careers of various members of the production crew.
The overall critic rating according to Rotten Tomatoes is 86%. So the critics were raving, over a horror comedy. That's rather rare, if not unprecendented. And yet its response is lackluster. So, if whoever wrote wikipedia up is correct, where's the smashmouth? Who's the pied piper with the forked tongue convincing people that Slither isn't worth the popcorn?
