It's impossible for me to look forward to any film but Man of Steel at the moment...
But I think if it wasn't out this year, Thor: The Dark World would be the Superhero film i'd be looking forward to most, not Iron Man 3. I dunno, I've just never been a massive Iron Man fan.
Does look like there will be some cool moments in it though.
Just accept that this is the direction they have taken.
Then, you can either decide this version isn't for you and stop watching. OR you can decide to enjoy it for what it is - an elseworlds tale.
'In Elseworlds, super-heroes are taken from their usual settings and put into strange times and places - some that have existed, and others that can't, couldn't or shouldn't exist. The result is stories that make characters who are as familiar as yesterday seem as fresh as tomorrow.'
