Anyway, last night I watched "Rosemary's Baby" for the first time ... and it blew my mind. I cant say that it is any "Chinatown" because it definitely is not. But it is a grade A thriller through and through. I cannot begin to say good things about this film. It is beyond creepy and works well off of the material and Polanskis direction, and it doesn't use fast cuts or any of the garbage that horror filmmakers use today for cheap screams. This film sets a mood that is creepy as hell from the beginning and only builds from there.
I wont go in to detail for the risk of giving away too much for anyone who has still not seen this classic. The basic gist of the film is that a couple (Farrow and Cassavettes) move into a new apartment which has a history of witches that may or may not involve their neighbors. Once Farrow becomes pregnant the rest of the film is generally ambiguous and up to your own personal interpretation.
Another point of interest is the way the film was shot. Polanski, no matter how great of a DP he has on his films is very controlling of the framing and general layout and look of the film. Scene after scene you witness some very beautiful and interesting camera work (almost in a "Hitchcockian" style). You can see other great examples and perhaps even better ones in "Chinatown".
Overall, I cannot remember the last time a film had genuinely creeped me out so much. This is a gripping film that is worth multiple viewings, and will now be a part of my all time favorite films particularly in the horror genre. 10/10
