I'm not sure what intrigues me about this movie so. It is grainy, poorly written, bleached out, often ridiculous, and at many points mind numbingly dull (the person I was watching it with fell asleep twice.) And yet there is something in this film that fascinates me, though I am not sure what; perhaps the character of Sam, an enormous former patient who was lobotimized by the former head doctor and who is perpetually sucking on an ice pop), or the marvelously played head doctor (I forget her name).
Anyway, watch it and form you're own opinion; it has one of the greatest endings I have seen in film.
