Did anyone watch all the way through to the end of the credits?
I watched it all the way to the end because I thought the music was really beautiful and resonated with how I was feeling once the movie finished (especially the second part of the track). Anyway, once the heart monitor noise starts an image of someone sitting in a desert landscape flashes in time with beep. I don't know if it was meant to be Alice but I thought it was a nice touch.
Anyway great movie, I've never had a film evoke such a feeling of sadness after watching it like this one did.
