As with my Mass Effect thread, I'd just as soon dispel with the spoiler tags. As I said in the Movie thread, if you haven't seen it, you do yourself a diservice seeking out any info beforehand. If you're the least bit interested in this, back out, go see it, and come back. We'll still be here.
Now, with that out of the way, did anyone else get the feeling that the third act was a direct result of Whedon's tv budget limitations on Buffy? I feel like the elevator doors opening were the release off all his pent up creative juices that had built up over the years.
The movie's not perfect by any means, but the structure, the layering that goes on throughout is pretty darn close, in my opinion. Really gets me pumped to see what Joss learned from this experience and applied to The Avengers.
