The plot is stock action movie. A teenage girl bred & trained to be a killer must defeat forces bent on destroying her. It’s also a weirdly artsy coming-of-age movie. A silly conceit is that Hanna only knows music from the dictionary definition, but In her travels she gets to discover music from many different cultures. I liked how they wed action tropes and a sense of wonder. Don’t think about it too hard and Hanna is an fun film of self-discovery and graphic violence.
