Well, I liked it too. It requires a lot of patience, though.
I agree with you on that, Rev.
The biggest issue with this movie is that it basically wasn't made for everyone to like. No snobbery involved. Some people like their films fast, loud, and frenetic. Others like their movies to be slower, to meditate on their subjects. This is clearly a case of the second type.
I can understand people walking out of this film. Do I agree with that response? No, but I'm not going to think someone is stupid because they found this movie boring. Some people like pop music while others like Tuvan throat singing; neither are wrong, just different.
Personally, I liked it a lot, but it isn't something I'll revisit often.
