I didn't see Iron Man 2 until after Avengers, so I never got to experience Thor's hammer in real time. The ending to Thor with Loki seemingly infiltrating SHIELD was a really kickass moment that seemed to foreshadow what was to come. Thor: TDW had the most exciting comic book moment for me (it placed both what had happened and what was to come in a different light). I almost voted for either. In the end, though, I had to go with the first. Samuel L. Jackson as Nick Fury changed the stakes of the game for me. It made Iron Man about more than just Iron Man and made me realize that Marvel's plan was far bigger than I thought possible.
