Query: Of course the book was better

I've always liked Robin Williams, and I grew up reading Isaac Asimov. That's the problem. I'm sure that if you never read the novella, you really enjoy the movie. But like most people who read the story first, I can't get past the fact that the storyline was butchered for the sake of making the movie. Asimov rarely included romance in his writing, and what little he did wasn't included in Bicentennial Man. Maybe if they just called it something else, or said "loosely based on ideas and characters created by Isaac Asimov."For those of you who have never read Isaac Asimov's original, enjoy this movie. It has special effects and a storyline you don't already know, and one of Robin Williams's better performances. But if you've read the book, don't disappoint yourself.
