Despite being a vampire movie there is a low amount of blood/gore in it.

There's one scene where a guy has landed on a wooden stick which penetrates him. Quite bloody. There's another scene where there's blood on the wall and a vampire goes, "Such a shame if it were to go to waste."

A few vampires get killed and turn to a grotesque ash (not too gory).

Wolves attack people and vampires bite people. People are attacked with weapons. All of these are not at all bloody/gory.

$hit is used a few times. There's a small amount of other profanity. It's quite low for an R film or even PG-13 film, especially since teenagers are mainly the stars.

Light. Moderate if any.

The film is bit done in a 17th Century way, so it's not your typical today's vampire movie. The main bad guy is very witty and makes witty comments.
