Disappointed this was a lot less tense the second time around but it's a masterpiece regardless. I love the way it plays with paranoia and has you questioning everything on the first watch, I think having all the answers detracted a little and that's why it's going to hit the hardest during your initial experience.

Now TV's movie description called it "birth control in movie form." Diabolical is the word I would use.

PS - The only demon here is Polanski and I hope he gets what's coming to him one day.
