The overall style of the series has a very strong video game feel to it, with different characters having different fighting styles and strengths (at one point main character Takashi even assigns them all roles in a typical RPG party). This is truly a series for the Resident Evil generation.
Highschool of the Dead is a fun, compelling, and beautifully drawn series full of energy and quirky nods to various other anime/manga/horror movies/video games. It's very tongue-in-cheek, but it has a tragic serious side as well. We can only pray for a speedy (and uncensored) U.S. release.
