First it should be noted that this is not so much a comedy as a comedy/drama. The comedy parts are indeed funny, but there aren't that many of them. The drama parts are desperately slow and dull, but the entire movie is absolutely rife with metaphor and symbolic meaning. Also, the acting performances are fantastic.

So if you're the kind of person who likes to think about every possible idea the filmmakers could have been intending to communicate in every scene, then you'll have a great time with this movie, but if you prefer a story that moves from plot point to plot point at a reasonable pace, then you might find this very hard to sit through.

Personally, I felt the filmmakers were trying to beat me over the head with symbolism, metaphor, and atmosphere to try to make a point that most people already agree with.
