Can 17 year olds watch R rated movies or do you have to be 18?

With an adult

If you can drive a car, you can see a movie

Often there's 4 movies playing. You face the movie you want and tube in to that movies sound. So long as an 18 year old is the driver of the vehicle, and the other occupants are not 7,year olds(obviously underage) there shouldn't be a problem

They have not checked IDs for movies any time that we have gone. It is up to parent discretion.
