I'm curious about how they handle the adoption themes. This review makes me feel a little hopeful that they're not shying away from some of the hard issues:
Kung Fu Panda 2 is a story about adoption. Po's reaction to Mr. Ping not being his real father is akin to what many adopted children must feel when they learn the truth about their birth. Was I not wanted? Why am I here? Who am I really? Doubt creeps into Po's psyche and endangers everything he has learned about himself. The ugly spector of failure rears its ugly head. But Po is not alone, or unwanted. He has powerful allies - his friends, his father, and most importantly, the teachings of Kung Fu. The search for inner peace leads Po to the discovery of an awesome power, inside him, that even the weaponry of Lord Shen cannot defeat.But my bet is that it'll turn out that he just doesn't need his birth family after all, instead of talking about needing/integrating both families. I hope I'm wrong, but am I? Just put "SPOILER ALERT" at the top of your comments for the benefit of others, but I'm too curious not to read any spoiler offered!
