What a weird way to tell a "What if the Avengers died?" story ...
It wasn't even a 'What If?' story, the story this told is 'What if Hank Pym went crazy?'
They should've re-interpreted the story of The Avengers movie, not re-telling the Thor and Hulk movies. The first two episodes were decent, they addressed the premise of the question.. This one didn't even answer the 'What If?"' Like, okay what happens when Loki attacks New York? Well, Captains America and Marvel form the New Avengers. Okay, show me that, don't show me the Avengers being murdered.
