There is not really any physical violence during the series except for one fairly intense scene that depicts a person being stabbed multiple times including a somewhat cringe worthy stab to the face. It's not gory but blood is seen (though probably much less blood than there would have been in real life) .

A young boy is hit by a car, his body is thrown brutally across the road.

Profanity is surprisingly very sparse and not very severe in this series. For example, In the first two episodes there are total of: 1 Damn, 1 Goddam, 2 God and 1 OMG. Throughout the rest of the series the profanity remains very mild. One episode has 2 instances of "shit" right after each other but that was probably the harshest profanity you'll hear in all 8 episodes. There are no "f words" or uses of Christ's name at all.

The F-word is used once throughout the series, in the 7th episode.

Characters drink beer, wine and spirits, but nothing to excessive.

The entire series has a has an underlying feeling of dread and of something not being quite right. It's not like horror movie dread or suspense but some viewers might find it frightening or unsettling.
