If you are of the faint of heart, this is not the right movie for you. The violence is almost non-stop, and it's incredibly disturbing and personal. I watched this before bed, and could barely fall asleep the plot haunted me so much. The story is well written, but the end seems like the writers got bored, and cut it off before the whole thing could play out...... But then again, it's more about the journey than the destination! Unlike most action movies, there is no humor whatsoever in this film. The main character is over-stressed, and throughout the movie, the more you get inside her mind, the sicker the feeling. In one scene, she pretends to act scared while coddling a woman (she's captive), and you see the innocent look in her eyes; but that changes within an instant, when she breaks the woman's neck. Startlingly dark, well-written and superbly-acted, Hanna will leave you shaking with the ever-hanging suspense........ Even after the end, you'll be waiting for what's next.
