Interesting...
I thoroughly enjoyed this film, its inexorable albeit slow pace didn't detract from the experience. It was like a big puzzle slowly coming together in front of you, and although it had a bit of a surprising climax, the ending was somehow a bit lacking, although if it had gone on any longer it would've begun to seriously drag. Worth seeing, it will challenge you to really think about what you're seeing, but not something I'd probably watch again...
