Here's a brief look at the content found in this R-rated thriller. Violence is extreme with many people being killed in all sorts of ways (including with varying weapons), often with extremely bloody and/or gory results. Other, non-lethal violence is also present. All of those scenes, others (including several "jump" scenes), and/or the whole Satan conquering the world element may be unsettling, suspenseful, or frightening to viewers, depending on their age and tolerance for such material. Bad attitudes rate as extreme as well.
Profanity is also extreme, due to at least 20 uses of the "f" word, while other profanities and colorful phrases also occur. An imagined sex scene shows a man having sex with a woman while her adult and partially nude daughter pleasures herself, while other sexual material, nudity and some related dialogue are also present. A character is initially suicidal and an alcoholic -- all related to the previous violent deaths of this wife and daughter.
Due to the amount and degree of the material that's included in this film, we suggest that you take a closer look at the more detailed content should you still be concerned about its appropriateness for yourself or anyone else in your home.
For those concerned with the repetitive flashing of bright lights on the screen, some moments of that occur in this film (at a near strobe-like rate).
