Many sexual references throughout.

A woman and a man start making out, but they stop.

Overall, brief but graphic violence.

Strong language like "f*ck", "c*ck" or "sh*t", mostly said by a possessed nun.

Casual drinking/smoking.

Some scenes involving exorcism and brief gore can be intense.

The possessed characters can be creepy.

Despite the "horror" tag this is more of a dark comedy/drama, but it does have an eerie tone, especially in the second half.
