Several episodes deal with mature sexual themes.

In episode 4, a woman takes her shirt off, but then covers her breasts with her arms so that nothing is seen.

In Episode 6, a man spies on a woman through her window. She is shown in revealing clothes, and her butt is partially revealed at one point. A man climbs on her in bed, but then they're interrupted before anything serious is shown.

Infrequent minor swearing. One use of the 'f' word in Episode 10, but that's the only occurrence throughout the whole series.

Mainly serious and potentially difficult subject matter.

Decalogue V features two deaths, one murder and one execution (both are not fully onscreen, not graphic). Both of which are extremely hard to watch.

The last 25 minutes of both Decalogue I and IX can be hard to watch for some viewers.
