Exit through the gift shop was pretty good. If you want it, PM your address and I'll send it out. I'm not watching it again.
I don't want to talk about it too much and spoil it for you, but at some point I started to feel like I was watching a spinal tap style mokumentery. I've got to do some Googling to figure out what I actually saw.
By the way, If any of you haven't seen Spinal Tap, you have to watch it ASAP. It's one of the top 10 funniest movies ever.
