I often enjoy "bad" movies, few films are as entertaining as "Glen or Glenda", "A Crack in the World", "Roller Boogie", "Assault on a Queen", etc. I will intentionally watch these films for the inherent comedic genius. So I will confine myself to the movies that I thought were bad that did not amuse me...
1. "Eraserhead"
2. " Very Bad People"
3. "Moon in the Gutter"
4. "Liquid Sky"
5. "Revenge for a Rape"
I'm sure there are more, but these immediately come to mind, "Eraserhead" was my instant reaction when I read the thread title; truly a pointless waste of time...
