I agree. This actually ruined it quite a bit for me. The movie was redeemed only by the moment when The Vision is carrying The Scarlet Witch in his arms - I loved their storyline, so that made me get all sentimental.
It would be nice to have better villians in the Marvel movies. Other than Loki, they've really only been forgettable plot devices to drive forward the heroes' stories and not much in the way of characters in and of themselves.
My favorite Marvel villain is Carnage, but they would have to make his storyline PG for a film - which totally defeats the purpose.
The other one is Dark Phoenix. They screwed up so bad I'm still not over it, although I was somewhat placated by the memory sequences in
The Wolverine.
In order to like any of these films besides
Thor, I have to pretend I haven't been reading comics since I was five. That way I don't get so ticked off and can just enjoy the movie.
