Saw it at midnight opening day. Smoked a fat king-sized before, and I think it was a little too indica to allow for serious movie watching. I actually fell asleep in the middle (I know, I know) but was able to follow. Liked it, but knew I had to see it again. So I did, soberly. This movie is really good, but I think the creative license was used a little too loosely in its writing. I'm not really a science fiction guy, so maybe it's just me, but I thought it pretty stupid the way they explained most of the technology and the rules behind it. Something about dream-sharing doesn't make sense? Don't worry, Joseph Gordon-Levitt will explain it in a few words. Of course, that didn't happen TOO often, but you catch my drift. The ending was perfect.
