Going to see rocky horror picture show thing with my mom and a friend but i am not 18 so can i still go even though my mom is going and buying the tickets?

In my experience theaters allow underage viewers into R movies when accompanied by a parent.

I googled RHPS and wasn't Abel to get the parental rating.

Yes you should be able to go if your with your mom or an adult

Yes

As ling as you're with your mom, you should be fine. But it is always a good idea to call and ask or have your mom check when she buys the tickets.

Yes you can

If your mom is going that should be fine, but I would call ahead and ask just to be sure.
