There are a few that are quite good like Requiem For A Dream. Movies that are very hard to watch and even worse to re watch. I was watching this movie Ketchum's The Girl Next Door. I just caught the tail end of the movie but it was so hard to watch but it didn't move me to watch it again, not even to understand the whole thing. I felt dirty just watching what I watched. Any other film you consider hard to watch? Or am I just being a little hard on movies? Oh yeah, Another one that is hard to watch is I Spit On Your Grave, I was watching it on Netflix but darn, too much for a 1970+ movie. I couldn't continue watching it.
