I certainly would like the claymore series continued. Unfortunately there isn't enough manga material to begin a new season yet and I'm not sure when they'll eventually start one
I got totally bugged when Trinity blood got over. It left too much unsaid about how Abel Nightroad is brought back to life and how he fights crusnik 01 after fusing at 100% and I thought it was incredibly lame how they just ended the anime saying that Abel was going to go after Cain. No mention of how Cain survived Abel's attack in the first place and how the panzer magier is going to help him get his body back. I guess the reason I was so miffed was because I like the anime so much. All good things do come to an end I guess ^_^.
