Action packed, fun characters and once again, Marvel plays the humor card extremely well.
If you're a fan of the first movie and other Marvel films, you'll most likely enjoy this. Same goes if you're not a fan.
From a parents perspective: Extremely violent, but like the Avengers, the violence is geared toward non-humans and fictitious beings so it has an element of not seeming as graphic or harmful. The violence is very similar to the other Marvel films.
