All of Us Are Dead
This Korean zombie horror series follows high-school students fighting for survival after a virus outbreak turns classmates into the infected, and it earns its TV-MA rating decisively across every episode. Alongside relentless gore and body horror, the series includes graphic bullying, a sexual-assault scene, strong profanity, and frequent jump-scares throughout its twelve-episode run.
Adults and very mature older teens only; this is not suitable for children or younger teens.
Episodes to know about
The very first scene shows a student brutally beaten and thrown off a rooftop by bullies; zombie attacks with blood and skin tearing begin before the episode ends.
Graphic school bullying that edges into sexual assault is depicted in the opening episode, catching many viewers off-guard; Netflix was criticised for not flagging this in its content warnings.
Early episodes establish both the zombie outbreak and severe bullying subplots simultaneously, making the opening stretch especially intense on multiple fronts.
