I liked IM3 but agree too that it wasn't in the magnitude of #1. At least #3 had a villain but their tale on extremis made no sense, all that heat (uh, boiling blood, tissue necrotization while you're hot, and so on) hurt the film, but it was so much better than 'drunken jerk Tony' in IM2. My sons liked IM1 the best, hated IM2 (won't even watch it on Netflix or iTunes) and liked IM3.

IM1 or Avengers, which is Marvel's best?
