[Alcibiades]

*SPOILERS*
The films ending is certainly open to be read one way or the other which is a beauty of the presentation. I'd contend that there really is no right answer to the question.

to KillSmiley: I've accounted for her brothers presence simply by the fact that time becomes meaningless after the fairty tale turn at the end.

Personally, when I first watched it, I cried during the end, but still took the fairy tale interpretation as what it read to me. While debate will never bring a conclusion to it, it's a movie that certainly needs to be talked about and discussed.

AND WATCHED! It's the kind of movie I reccomend to anyone, so long as they don't mind subtitles. Either you'll appreciate the visual direction, the brilliant storytelling, or both.
