Im going to say that HOTD is awesome, I mean its setting is based during a zombie apocalypse, sweeett; and yes, there is a bit of a overdose of fan service but the action outweighs it in my opinion. The plot is interesting, there's drama but ya know, its gonna happen. The characters are "common" but they are "unique" in their own way.
But on to the important stuff, the zombie apocalypse setting is an awesome idea. Plus, the highschoolers face a struggle with adults still bossing them around yet they are mowing down zombies while them adults aren't doing jack-squat.
Bottom-line: HOTD is pretty awesome and I hope season 2 comes out soon.
