I don't think there's enough action in the movie.
It looks like it's going to be pretty cool and pretty big. I fear, though, Robert Downey Jr. may steal a lot of the spot light. At least, that's how it's being advertised (Iron Man front and center, while Cap stands in the back... not to mention a lot of the trailers consist of either Downey Jr. or Iron Man scenes).
All in all, I look forward to it.
