I just finished watching both
Happiness and
Kids (which I had no idea has Chloë Sevigny!), and I think I'm now thoroughly disturbed. Kids is a good example of why I'd be terrified to have kids because I'd be a bit sad if they had that kind of "secret" life. But I'll have them anyway.
My top disturbing movies in no particular order:
1. Happiness
2. Kids
3. Gummo
4. A Clockwork Orange
5. That's all I've actually seen.
