Some episodes might have sex but nothing overtly dirty, at least not yet. That could change.
Violence & Gore
Unrated
Some episodes are about violence in the community, but so far not graphic. That could change in the future and make this a more hard R/18 type show.
Profanity
Unrated
Graphic language, as in one episode the F-word is said 3 or 4 times (this is a 10-minute series, not a 20-minute one), but not to the point of it being hard R (18 in Schengen Area). Perhaps it'll change in the future.
Cinemax content advisory: rated TV-MA for graphic language (GL) and adult content (AC). BBFC/Schengen Area rating 15. Perhaps it'll become more hard R and 18. Sometimes it's TV-MA-L or TV-MA-DL.
