[neverending]

If the mother was a REAL person, and not a character in a movie, obviously I'd feel emapthy for her. Some movies or actors are so good that they kind of make you "forget" that what you're watching isn't real, but that's not the case with Rosemary's Baby - in my opinion.

I guess you'll have to be content to be in the minority on that point. Mia Farrow was nominated for a BAFTA and a Golden Globe for her portrayal. Variety called her performance "outstanding." Rotten Tomatoes consensus on the film (which maintains a 98% fresh rating) states "A frightening tale of Satanism and pregnancy that is even more disturbing than it sounds thanks to convincing and committed performances by Mia Farrow and Ruth Gordon." Ira Levin, who wrote the book, liked her performance so much he dedicated his sequel to her.

And of course, the status of the film as a true classic, which it would not be able to maintain if the performance of the central character was weak.
