I like the show, but I agree that the music may have been the best thing. It was of a consistently high quality, while the episodes were hit or miss.
Obviously not every single episode was a "classic" but I'd say it had to be "consistently high quality" to sustain its appeal all these years. "Hit or miss" doesn't exactly capture that, and I'm just astounded that anyone could find greater pleasure in the music than in the stories themselves. In all seriousness I can't say that I have ever made note of the music at all.
Dan, that's fine. However, a number of great respected composers contributed to that show, including Herrmann, Goldsmith, Leonard Rosenman, and many others. It was a great period for film and TV scoring. The sensibilities of composers from that era combined with the sci-fi/fantasy elements of shows like "Twilight Zone," "Outer Limits" and others meant that composers could really stretch out in terms of color, effect, etc. You may not have noticed the music, but the opinion that the music is the best part of those shows is hardly an uncommon one. For what it's worth, I have the 4 CD TZ box set and the 2 disc Herrmann TZ set, yet I don't own a single episode on VHS or DVD. I prefer the music to the show, though there were some very cool episodes. I try to catch it on the Sci Fi channel every now and then.
