No sex or nudity. Two characters undress to skinny dip but are seen only from the thighs down and waist up. One character tells a smutty joke but it doesn't translate in the English subtitles.

None really. It appears to rain blood at one point, and many fish are seen dead. A character stands on some grasshoppers / locusts.

I think I noticed 'shit' a couple of times, but infrequent and not intrusive.

Beer and wine drunk throughout but not in quantities to change behaviour significantly.

Mildly apocalyptic theme. An older character seems to be possessed at one point, and is thought to have died at another.
