You can't spell slaughter without laughter! This splatter fest is a true classic with a bouncy synth soundtrack you won't be able to get out of your head no matter how hard you try. Meet Marty, an awkward highschool hipster who is relentlessly harrased by his duche bag classmates. At one point they mock him by chanting "where's the beef?". It doesn't get much more 80s than that. Their bullying goes too far and results in a chem lab mishap that melts Marty's face off.
So he does what any normal guy would do and bumps his tormentors off one by one in the most needlessly elaborate ways possible.
Honestly, the movie is probably 97% shower scenes.
The finale consists of two or three WTF plot twist endings. It kind of deteriorates into a music video for Slayer or possibly Dokken. Well worth a look none the less.
