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.
My God, did that smell good!
With proper execution, ANY movie idea can work.
