It had some pretty cool moments (Toboe taking down the mother fucking monster in the ice wasteland, anyone?) and some equally depressing ones (CHEEEEEEEEEEEEEEEEEEEEEEEEERRRRRR!!! ;~;)
...But, what made watching the entire show worth it for me, was that epic fucking fight with wolf-Darcia in the last episode. Jesus christ, he went absolutely batshit loco.
Overall, decent show. Not one of the best, but hardly the worst.
