None but a man tries to harass a girl but is stopped also inappropriate jokes.
There is a scene of harassment, but it is not clear... The man approaches the woman, but there are no clear scenes.
Violence & Gore
Severe
Average zombie series, zombies are seen killing peoples but only blood splatter is shown. Zombie also bites a main character mildly severe.
The first episode makes this seem like a high school comedy. That delusion ends in the 2nd episode where the extreme blood, decapitations, stabbings and excessive gore begins and the mutilated / killed body count goes from one to dozens.
Profanity
Moderate
Few uses of "f***". 10 uses of "s****".
In Korean, there is a lot of profanity suck as f*** and b****
Alcohol, Drugs & Smoking
Mild
A few scenes of people smoking.
Frightening & Intense Scenes
Severe
There is some relief between intense scenes.
Most deaths are onscreen, or at least partially.
Deaths could be shocking or startling.
Beginning in episode two the attacks by aliens are extreme and severe, with highly visual human mutilations, dismemberment, decapitations and more.
