Let's not forget the horrible green screen backgrounds when Indy is first kidnapped at the beginning when he takes his hat from the ground...which itself was one of the worst blocked scenes I've seen in some time, as well.
What did you expect from a George Lucas movie? Acutal actors? Actual sets??
It's a Steven Spielberg movie.
I thought they collaborated? Lucas IS on the DVD extras. Unless you're talking about strictly the director, which I wasn't.
