I've seen this film dozens of times, but today, I was at my mother's and she was lamenting the fact that it was close to Halloween and there were no good horror movies on.
She kept scanning the channels, then I noticed her pass up Suspiria, which would be coming on in five minutes.
I was all, "WTF, mother. Suspiria is a great horror / suspense film."
So I made her watch it.
And her mind was blown.
The end.
