10 Even More Insane Over The Top Horror Movies

10. Bug

Based on the 1973 novel The Hephaestus Plague, Bug follows a mad scientist, Parmiter, who's obsessed with breeding an intelligent sub-species of cockroach. After Parmiter's experiment proves successful, the super-insects invade a small town, wreaking havoc on the locals.

On the surface, the sci-fi horror doesn't sound too different from any other campy creature feature. However, there's one thing that makes Bug the weirdest kind of monster B-movie: the cockroaches shoot fire. By rubbing their legs together, these calamitous critters can incinerate anyone in their path, leading to many moments that are more comical than frightening.

Just when it looks like the zaniness has peaked, Bug will toss in another nutty idea, like when Parmiter learns he can speak to his creations or how the pyro-beetles can use their bodies to spell out words. It's also funny how Bug attempts to stay grounded in reality by delving into the science behind how these fire-roaches evolved, as if these sentient flamethrowers could actually exist.

It's far from scary, but Bug is still entertainingly bad due to the poor special effects, ludicrous plot, and over-the-top acting.
