The MPAA has given a low budget movie called "My Son" an R-rating, even though there is no bad language, sex scenes, or nudity.
The movie was made by the congregation of a church (Retta Baptist) in Burleson, TX and did have some violence and a little drug use.
But the violence wasn't gory or gratuitous.
Compare it to the film "World War Z" and "Bully" with both got PG-13 ratings and "Jobs" which had scenes with LSD and pot use also got a PG-13 rating.
The church thinks the R rating is because of the movie's faith-based messages.
The MPAA says the same rules apply to all films, and they don't comment on why films get the ratings they do.
The church has asked what they need to take out to get a PG-13 rating but haven't heard back.
