I haven't seen Happiness, I can't it find it whenever I go looking for it. >.<. I'm all set to go and see his new one, Dark Horse. I liked one of the featured press grabs promoting the movie: "No one stages a bad party like director Todd Solondz". Hah.
Yeah good point. That role reversal, for want of a better term, really made me ponder comfort as it relates to (cognitive) dissonance. Made me think about people I've known who are only happy when things are chaotic. I loved looking at everything through that little prism for a while. Definitely have to make some time to watch that again. I don't think I would have had I not come across your post. Yay. Also, it's just gorgeous and soothing to look at.
I left out Requiem for a Dream. Though, that didn't really hit me very hard until I saw it a second time. And another one I saw which was a little twisted up was Little Children. I know I've seen some other really good films that fit the bill. Will have to ponder.
