For all that Kenneth Branagh gets dismissed as not having a handle on the action parts of Thor, I still think that first big fight scene for Thor in Jotenheim was the most impressive of all. I loved the Iron Man/Thor fight in Avengers, but nothing has beaten that first fight for the wow factor. And that's a shame.
Part of the problem is that no matter how many bad guys Thor is swatting off in his fights, all the other Avengers are equally able to do the same, even the ones without any superpowers. He might use a steel girder while they use another less heavy weapon, or magic, or speed, but the outcome is still the same.
And unfortunately most scenes that involves flying are allocated to Iron Man.
I really hope they can work out how to make Thor do something with the wow factor again.
