Memento
I wasn't paying full attention, so it barely made any sense (again) and this movie makes my brain hurt anyway. Permanent short-term memory loss would be awful. For some reason it reminds me a lot of The Machinist, which I also didn't much enjoy. Films about people with sleeping problems, or memory problems or dreams... my bf seems to love them. They just make me cringe. It's sort of like a 'disability thriller' or something.
...Not that it makes me cringe for that, more because I don't much like stories told backwards or out of order or in a deliberately confusing-as-hell way. Insomnia was okay, though. Robin Williams = creepy.
