Oh I know of a good light hearted movie to make you feel better after RFAD, it's called Trainspotting What else... The crying game, also a good movie, and the girl is really hot, I'm sure you'll like her...
Fountain, not so much disturbing, it's really more of a fantastic 'wtf is going on!' movie, not bad if you like that sort film, somewhat reminiscent of the weird stuff by Lynch or Cronenberg, but in a lesser weirdness level...
