I had to watch it in school as a kid, and the idiotic teacher didn't comprehent why 16yr old kids were not interested. The fool was probably stuck in a trip as a hippie.
No but it might keep you from getting as nauseated.
I've seen it once, and no, I didn't get it, but I think it's one of those movies you have to watch several times to understand it..... drunk or sober, like "Clock Work Orange."
I always thought it was awful whether or not I was high haha.
