I'll recommend it to my daughter, she likes scary movies.

It has a strong 'R' rating, there is "some" amount of gore, not it's not your typical slasher movie.

Unlike the movie Saw (where it's customary to have a touch of twisted sympathy for Jigsaw), there is zero sympathy for the "evil force" in this movie. "Prince of Darkness" is almost universally acknowledged as a powerful movie.

(A person with strong Christian beliefs who finds anti-God movies distubring, should NOT watch this movie. While I laugh at movies like the Exorcist, this one won't leave you laughing...it scares you)
