I loved this film. I loved the quirky humor and the fact that it seemed the whole point was that there was no point. There were some great one-liners as well, such as, "You can't deal with my infinite nature, can you..." I liked the concept - everyone asks big questions about meaning and life and where we're headed and everything. The movie simply put a bunch of very dedicated people together who were all struggling to find answers to their questions. Also, the film presented most possible "solutions" to the big questions, including, "everything is meaningless," "we're all connected, and everything matters," and even religion (though I don't think that it was necessarily an accurate description), without really answering the questions at all. I really think that these questions shouldn't be answered in a film anyway - it's a drastically didactic move.
It surprises me that people felt the film was slow-moving and dumb. I think one critic had it right: "Don't think about this loony metaphysical comedy too much. Just go with it and, chances are, you'll get it." I think that hits it on the head. The film deals with very real, very deep, very important questions - but don't take it too seriously. It's a comedy, and not a sermon. And seriously - I want to see it again. And again... :-)
Some good quotes:
Albert Markovski: Nobody sits like this rock sits. You rock, rock. The rock just sits and is. You show us how to just sit here and that's what we need.
Vivian Jaffe: Have you ever transcended space and time?
Albert Markovsk: Uh, Time not space... No I don't know what you're talking about.
Girl: Jesus is never mad at us if we live with him in our hearts!
Tommy Corn: I hate to break it to you, but He is - He most definitely is.
