The movie came out when I was in high school also. Thing was, they slapped a then new NC 17 rating on it.The theaters around here (all two) upped it to 18+ when more than a few phone calls from concerned parents were made. Raising the hackles on the local Catholic Cardinal's neck didn't help either. He advised that Boston area Catholics shouldn't watch since it went against church doctrines. So I waited till it came out on VHS, and saw it then. TBH, it disturbed the crap out of me the first time. It wasn't the stuff on the screen so much as it was the theological idea of being possessed like that. Since then I have read about people being killed during the exorsism rite. I think that even if I wasn't raised Catholic, that kind of thing would bother me.... whatever. I have no illusions about church anymore. As a piece of film though, it is a classic. It makes you think on some level. You either watch it again, or not.
