Just finished Highschool of the Dead last night. Would I recommend it? Well...
Great animation
Great voice acting (Seriously, Johji Nakata, Miyuki Sawashiro, Junichi Suwabe, Nobuyuki Hiyama, come on)
Good characters
Good action
Good dramatic scenes and stuff
But of course, with this show the question is "Are you going to let gratuitous fanservice ruin an otherwise great show for you?"
So if you:
A) Hate fanservice, and think it ruins any anime it's in
Then: Stay the fuck away
B) Don't like fanservice, but could tolerate it if the show is good
Then: If you like zombies, watch. Otherwise, don't
C) Don't feel one way or the other about fanservice
Then: Watch it
D) Like fanservice
Then: WATCH IT
E) Love fanservice
Then: You will die of pure delight watching this show
As for what's coming out this season, I'm watching Star Driver (because it's fabulous) and Arakawa Under the Bridge x Bridge (because it's hilarious).
