What parents need to know
Parents need to know that this sequel to 2008's hit animated film about an unlikely martial arts hero returns to China, where Po (again voiced by Jack Black) and the rest of his kung fu clan must defeat a new villain who's armed with gunpowder and cannons. The movie's surprisingly poignant, sometimes serious story addresses the conflict between tradition and modernization, as well as Po's discovery of a long-hidden tragedy and his journey to accept an unusual upbringing. Not surprisingly, there's plenty of action -- including explosions, swordfights, and lots of kung fu fisticuffs. Scenes involving parent-child separation could also be upsetting for kids. Unlike the first film, this one is offered in 3-D, which can make some of the sequences feel more intense.
