Night of the Lepus was just plain stupid. I remember wathcing it at a sleepover at a friend's house when I was a kid- on weekends my friends & I used to sit up & watch the late-nite horror movies & eat junk food until the wee hours. I remember feeling ripped off by those stupid rabbits- where was my REAL horror movie?
As for Eraserhead, well... wow, don't know what to say- I've seen (or tried to watch) it "chemically enhanced" (as a much younger adult) and without chemical interference (as recently as a couple of years ago) & never made it to the end. Too weird for me and that's saying something.
