Disclaimer: The following is just my personal opinion. Music is different for each person. Keep in mind, I like dark, muscular, thematic orchestra and throbbing synths (Tangerine Dream sounds, ROBOCOP and STARSHIP TROOPERS, etc.).
After seeing the movie, replayed, about a month ago, I Amazon ordered the MEET JOE BLACK CD (yes I live in the past) It has one or two themes that blow me away - up there with the best, but the CD as a whole is kind of boring for me.
And frankly, I'm stunned that anyone would suggest his quality of worked dropped off after Jedi. I mean, Jurassic Park!!!
I stand by what I said, though I reworded this paragraph to say that JURASSIC PARK is an exception. The main theme is fantastic. The rest of the score seemed good, but not enough to make me want to hear it in isolation...until this conversation. Perhaps, I'll give it a closer listen.
I believe that Williams peaked with EMPIRE (Vader's theme, the Asteroid Field, the wonderful heroes' themes, Bopa Fett, etc.) and E.T. When RETURN OF THE JEDI came out, it was the first time I was a little disappointed with a STAR WARS score. (A lot could have been the tone with the Ewoks involved. I can't stand them.) It was really good, but not up to his previous work. Also, the original release didn't have the best part - some of the Emperor scenes and the choir theme as Luke beats down Vader. I since got the full version and that made it much better.
As for the other scores since? You see what's in my picture. There is little outside of that J.W. collection that makes me want to listen further. WAR OF THE WORLDS and the new STAR WARS stuff sounded so empty to me. Sure, I liked the Dual of the Fates theme and the Anakin and Padme love theme. There was another, too. The rest didn't call to me, at all.
I'm a guy who bought 3 double albums of the original STAR WARS score, because I kept wearing them out on my record player. (Thank goodness for CDs.) Every song was great. The motifs of LOST IN SPACE were being channeled and elevated in a magnificent way. The first time I heard STAR WARS, it was already familiar to me.
So what happened? Was I just getting older? Nope. Scores like Steve Jablonsky's TRANSFORMERS and Danny Elfman's Music For A Darkened Theater compilations were blowing me away. The scores to OBLIVION and EDGE OF TOMORROW are fabulous. The former wakes me up, every morning.
Again, this is all my opinion. If I told you I went gaga over Bear McCreary's EUROPA REPORT soundtrack, you might think I'm crazy.
