I really enjoyed watching the series, however was expecting much more. Literally.
Biggest problem I had was the story...was just missing the build up the first season had.
I had searched for the new episode on the usual fansub release date expecting episode 12. Had to look it up to find out the series had actually ended. I was really expecting another 11+ episodes to this series, only in small part due to the length of the first season. After watching the last episode, I had no idea it WAS the last episode. It seemed more like the ending of a major arc, sure, but not the finale of an entire season. It lacked closure and left a lot of wanting.
