Still one of the best/scariest movies of all time. It gave my ex-girlfriend mental problems after she was forced to watch it by evil cousins at 8 years old or something like that.
We were at a Halloween costume place a few years ago and I said, "hey look, Linda Blair!" and pointed out this costume, and she got so quiet and pale. She didn't say anything for about 15-30 minutes.
I don't think most movies would have that effect. Oh, and she went to Catholic school, so that'll do it too.
