Wow. Just...wow. What else can I say? This movie was utterly brilliant, not only as a whodunnit? style mystery, but also as an emotional drama. It's one of the most tragic movies I've ever seen, as well as one of the most mind-bending mysteries ever. Even my dad had trouble keeping up! :-) The format was perfect, the directing fantastic, and... well, I'll just say it one more time. This movie was UTTERLY brilliant.
