This is a very cool movie. I wasn't totally sold on the premise based solely on the overview but there is a lot more to Hanna than just your run-of-the-mill assassin story. I didn't necessarily pick up on the "fairy tale like elements" while watching it but in hindsight, they were definitely there.
Saoirse Ronan is really, really good.
I also really enjoyed the soundtrack. The Chemical Brothers style fit perfectly with the pace and theme of the movie and got me bumpin' on more than a single occasion.
Overall, I give this movie an 8/10. I'm super interested to see what Seth Lochhead does next.
