So the way the movie constantly shifts back and forth between serious and Shakespearean to lighthearted and campy didn't strike anybody else as... odd?
Not me personally, as the tonal shift corresponded to Thor's exile to earth, but I could see how it might not be to everyone's taste.
Regarding Cap, I agree with some of the points made by Dac above, particularly the point that Bucky's death really didn't have any emotional weight. I still enjoyed this movie quite a bit, though, and would give it a B+ or so. Chris Evans did a great job as Cap. With RDJ and Hemsworth, Marvel is set up nicely for Avengers.
Oh and Hayley Atwell =
They need to find some way to bring her to modern times.
