Charlie Chaplin -- I appreciate his pioneering of the film media, but I have yet to enjoy him on the screen.
Abbott and Costello -- Comedy is my favorite genre but this team has never made me laugh. Never.
Barbra Streisand -- In short she has an arrogant method of acting -- always posing, usually over pronouncing her lines.
Jack Nicholson -- I've seen about a half dozen movies of his and he plays the same character over and over. And not that well. A local radio station uses a sound clip of one of his famous lines (paraphrase -- Don't sell me crazy. We're all full up here") and it's a pitiful reading.
