I think Spielberg let Lucas have too much influence on this movie. I mean, the other three films in the series had something to do about history, but this one was about aliens. It was almost as if Lucas convinced Spielberg to combine Indiana Jones with Close Encounters of the Third Kind. It was a good movie, but it was just so much different from the other ones. The only part that I didn't get was how a refrigerator could save the guy from a nuclear bomb. That was kind of... ridiculous.
