I feel a little silly posting this now, but while I too have gotten irritated at the 30-minute album trend, I find that there really ISN'T that much "essential music" deleted from some score releases. People were very angry when "Scream" came out with less than 30 minutes of score to represent TWO movies, but there really isn't that much of essential music left in the film.
Some movies seem like they have a lot more music than they do. I remember hearing of some great bootleg with the "complete score" to Zimmer's "Backdraft" and getting interested until I saw the film and realized that practically all the music in the film is on the album, other than a few source songs. It might be nice if Varese put two short Shore scores together on one release, but considering that this release would not have probably occurred without Varese's interest, I'm willing to give them a break.
