Its a nice survival horror, feels like an extended movie. Its one of those few zombie survival shows that isn't afraid of killing off well developed characters, which can be a good way to build tension and stress, or it could be a problem because now your fav character is dead. The story and plot is pretty basic but it has an interesting take on the origins, the guy who creates the zombie virus had no financial, political or narcassistic motivations: he wanted to create a serum that would help his son become stronger and more aggressive to avoid being bullied all the time. The "zombies" are not really your stereotypical zombies, they seem more like humans with rabies that have an extreme penchant for violence, they have a lot of tenacity and sometimes it makes for interesting scenes. It takes place in a high school setting, interesting character dynamics, good soundtrack, good acting and overall is pretty relentless with the tension. Sometimes it feels exhilarating.
