"Iron Man 2"
** 1/2 (out of four)
A couple years ago, "Iron Man" came out of the blue to immediately situate itself as one of the great superhero entries.
It lacked the scope of the new "Batman" films and the emotional pull of the first two "Spider-Man" movies, but it was embedded with such a bright, pop-bubblegum aesthetic and badass attitude that director Jon Favreau's lack of nuts-and-bolts filmmaking ability didn't really matter.
It was an experience that managed to be far greater than the sum of its parts — pure movie magic, with palpable energy and a grand sense of "let's go save the world" fun. "Iron Man 2" attempts to recapture that same flag-waving, fist-pumping fervor, with mixed results.
