Spielberg is far more varied come on. He started off as more of a thrill director, making summer movies as well as the types of movies people would go to in order to be entertained. But then he's equally as impressive with far more serious content such as Schindler's List, The Color Purple, and the criminally underrated Amistad. Then he's also very impressive with pure sci-fi projects such as Minority Report, AI, etc.
