Read Rosemary's Baby by Ira Levin.
Actually. Read EVERYTHING by Ira Levin.
Then see Rosemary's Baby with the incomparable Ruth Gordon. Realize that the book is better but the movie is still awesome.
And then cross your fingers and pray to whatever God you believe in that Michael Bay's remake either dies a quiet death or is so awesome that it makes the book look like crap. OR that he realizes NO ONE can be Ruth Gordon except Ruth Gordon so he decides to adapt Son Of Rosemary, since Ira Levin already went there.
