From the New York Times How to tell a bad movie:

Locate the exit nearest you, she says, before screening any film directed by big-name male actors or Brian De Palma, any film that features Robin Williams in a beard, any film scored by John Williams, any film starring Juliette Binoche or Kevin Costner, any film that features Robin Williams clean-shaven, any film directed by a woman and proud of it, any film that features Robin Williams in a yarmulke and any film positively reviewed by anyone associated with National Public Radio.
