I admire Robin Williams.His quick,improvisational humor make him the most unique entertainer of our time.However,he does from time to time make bad choices,and Flubber was indeed a bad one,at least scriptwise.This movie's problem is not from bad performances,but from terrible writing,and that often makes the performers look bad.The intentions here are good,but the movie just fell flat in all aspects.If you want to see a movie about flubber,I would highly suggest "The Absent Minded Professor".It's a classic and it's much better.
