Paul Rudd is cool. Maybe paying $12.50 to see it is a little overkill, but yeah, as long as you don't feel like you're missing out, hold off.
Interesting foreshadow after the end credits, of course.
I think that, in some ways, it was better than both Thors and the Captain America movies, simply because it didn't have all the dumb one-liners. If you can find a theater that's showing it for cheap, go for it! The AMC 30 here charges like $13; probably not worth that much.
