This is an artful and dramatic take on what is generally a thoughtless genre. Zombie film is generally brain dead (pun intended), and it's refreshing to see such an intelligent aim at a cult subject.
The violence is graphic, leaving nothing to imagination. This violence and gore permeates the portrayal. Anyone with violent tendencies or a weak stomach should think twice.
The sexual content is not explicit, and handled well. In the first three seasons, there are a total of four sexual scenes. One is dirty, and lasts about 20 seconds. One is impulsive, and has a crotch grab. This takes all of 5 seconds. One is not sexual but poses sexual themes. This lasts a minute. The last is romantic, and lasts around 30 seconds.
For adults, these are lightly provocative at worst, but for children and teens, I would advise consideration.
This has been one of my favorite series of late. Definitely worth a watch, if you feel like it's a good fit.
