Highschool of the Dead
Interesting choice ;)
One of the better made zombie anime out there, among other things.
Sword Art Online is good-ish according to my more avid anime friends.
The first part of season 1 is brilliant and then it goes downhill from there. Season 2 is a joke, I really hope it picks up a notch for the remaining episodes, but I'm not holding my breath :P
I'm curious as to when Kerosea is gonna drop off some suggestions? >.>
