TV version good for one reason.
I have both the R rated & TV versions of Private School.
The only scene worth having that is on the TV version is when Betsy Russell takes off her shorts. It has a different classroom scene at the beginning, Mooning scene at the end of the movie with their panties all the way on.
Much more of Phoebe Cates & Matthew Modine at the hotel.
So the only thing that should be on the R rated DVD is Betsy Russell taking off her shorts.
