1-9 were great, 10, 11, 12 totally ruined them. It discuss some moral topics between a girl trires to do the right thing and the world's reacts of it. But somehow it come to a end of conventional "love solves anything" . I'd say it's the episodes screenwriters to blame. You can even judge by the episode title, 10,11,12 is all about love while the rest is about Faith, war, Death. I'd give episode 1-9 9/10 and the rest 3/10.
