Jon Favreau's Iron Man 2 sadly doesn't match the great emotional highs of other superhero "part twos" like Spider-Man 2 , The Dark Knight or X2: X-Men United .
It's the fact that great-to-good comic book-style movies like " The Dark Knight ," " Spider-Man 2 ," " The Incredibles " and, yes, even "Iron Man" are interested and invested in clear, coherent and competent storytelling, while bad-to-bland comic-book-style movies like " Spider-Man 3 ," "Batman & Robin" and, yes, "Iron Man 2" are interested and invested in throwing characters on-screen and nodding to comics history so that comic book readers can use their normally useless storehouse of information about these mythologies to play connect-the-dots.
The superhero genre doesn't necessarily require good acting, but when it's there (as in " Iron Man " and " The Dark Knight "), that takes it up a level.
This "hero in crisis" idea works well for second installments of superhero tales (Spider-Man 2 and The Dark Knight mined it as well), giving us a little more character depth to go with the requisite amped-up action.
The hints of something as complex as a Dark Knight or Watchmen are so tantalizing palpable here that I’m frankly stunned that Theroux, who cowrote the brilliantly subversive Tropic Thunder, didn’t see it… or maybe I should be angry that he wasn’t allowed to go where this story is quite clearly itching to go (though that’s hard to believe after we’ve seen that moral complexity didn’t stop The Dark Knight from raking in a billion bucks worldwide).
Iron Man 2 doesn’t stand alongside the great superhero sequels like The Dark Knight, Superman II and Spider-Man 2, but it’s far better than the disasters that were Batman & Robin and Spider-Man 3. Favreau and Downey Jr. have done their jobs well with ultimately forgivable exceptions.
