Class of 1984 went straight to video and was controversial when it was released. The plot is simple...and awesome. Punk-rock, ultra-violent students vs. vigilante new music teacher in a fight to the death. Even though it features the loveable Michael J. Fox (credited here without the J) in one of his earliest roles, there are some pretty brutal scenes, especially at the end. The soundtrack is great as well, featuring music by Fear, Teenage Head and a terrible/awesome "theme song" called "I Am the Future" by Alice Cooper (I was shocked to find out he sang it!). Check out the trailer:
