Under 17 requires accompanying parent or adult guardian 21 or older. The parent/guardian is required to stay with the child under 17 through the entire movie, even if the parent gives the child/teenager permission to see the film alone. These films may contain strong profanity, graphic sexuality, nudity, strong violence, horror, gore, and strong drug use. A movie rated R for profanity often has more severe or frequent language than the PG-13 rating would permit. An R-rated movie may have more blood, gore, drug use, nudity, or graphic sexuality than a PG-13 movie would admit.
I only started to understand the movie after about 30 minutes. Frankly, it was boring. I was bored while watching it. Also, some scenes were absurd. The horror film relies heavily on dialogue. Is it worth watching? I think it's a waste of time. It gets a 2 out of 10. Moreover, I couldn't even finish the movie.
