Even if I wasn't old enough (I am) no theaters here actually care about ratings, R rating just means under 18 you require a parent but they will let any teenager watch it without parents because it's where most of their money comes from
I work in a cinema, and it didn't exactly set the world on fire with an advanced screening. It looks too childish for adults yet a 15 restriction puts off the immature kids who'd find it funny.
Officially the weirdest film I have ever seen; over use of swearing just took away from the jokes that actually were funny, I will never understand how this is only a 15. 1/10
