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.
MCU - $7 billion and counting. Next up: kicking Harry Potter's butt.
