Frequent violent killings shown in great detail. Eg, stabbings, shootings, hangings. The violence gets more mild in late series's.

An occasional "bloody" or "bastard." Otherwise no profanity to speak of.

One f-bomb in Series 11, Episode 1.

Alcohol is consumed in almost every episodes. Drugs are used sparingly, but do appear.

Especially in Series 1 and 2, tense scenes are very drawn out and are quite disturbing. There are several jump scare camera angles. There are no especially intense scenes post Series 3.
