I'm one of those people who wait to hear the score as it is presented in the film before I listen to the soundtrack by itself. I don't believe in judging a score before I get the full picture(or before I see the film). I believe that music has the most vital role in a movie. It's like the heartbeat of the film. It's the LIFE of a movie. It adds the majority of emotions to a picture. I also have great respect for Mr. Williams, and I know he did a good job (as always)! I expect it to be a great score and film, because the Williams/Spielberg duo is legendary!
Have you heard about Indiana Jones 4? Pretty cool! I'm sure Mr. Williams will still be around to score it even though it probably won't be around for a few years.
