Re: How do we avoid the third act curse?
Hmm, I actually really like the 3rd acts of both of those films. Now Spider-man 1 & 2 and X-Men 1 & 2 I had problems with in the final acts. Of course I thought none of those films were especially good to begin with. Adequate is about the best I'd give'em.
You know, it occurs to me that Captain America is basically the superhero equivalent of Mary Poppins. Practically perfect in every way and all that stuff.
