Ahh. See, I thought you were saying DD was great, and I was arguing that it wasn't great because of most of what you need in order to really understand it isn't even in the film. There's no way you could understand what was going on (unless you just happened to guess it) without getting outside info from the creator of it. Then there's this whole God the Father, God the Son, and God the Holy Spirit thing going on that's hinted at in different ways but not explicitly stated.
I like it for it's bizarreness in the missing information aspect, and I like it as a movie, but I certainly wouldn't rate it as one of the greatest movies ever. I think I'd give it a 6 or a 7.
When are we going to discuss the greatest movies of the 19th century?
