Re: How do we avoid the third act curse?
IM3 could be the first in the superhero genre that I've seen. But given that the whole idea of the MCU is to throw off the tired old trilogy formula and just have a bunch of James Bond-ish ongoing franchises that exist in the same universe I think it's pointless to apply the trilogy mindset to something like what Marvel Studios is doing.
MCU - $7 billion and counting. Next up: kicking Harry Potter's butt.
