"Iron Man 2" is just as charming as the first film, and it packs in even more action, humor, and great dialogue. It's relatively-clean and is a great action/comedy for superhero-fans wanting a good action-flick.
It packs a punch, but unlike the first film, it strays from terrorists and middle-east affairs and the scare-factor (and violence) was tamed down a bit. The violence consists of lots of Iron Man suit action (mostly against robots, and other suits) but there are some fist-fights, a brief boxing-lesson, an electrocution (not gory at all) etc. The little mature content that there is, is: Tony getting drunk at a party and showing off a bit, one kiss, some flirtatious-comments from Tony, and some banter between characters. The langauge isn't overt, but "A**" is used about 5 times, and one "s**t" from a villain. "Hell" is also used, but it is very sparse, and the language is VERY tame for a PG-13 film. (Though there are two uses of f**k, they are bleeped out for the film) Overall, it's a great film and sequel to "Iron Man", and should be enjoyed by people of all ages.
