Yep, I enjoy it too. Sometimes ya just have to call a spade a spade, and Berman was just not a good creative force in Star Trek, period.
You're right. He kept Trek on the air for only 18 years, that slacker. A good producer would go at least 30.

Berman certainly had his influences, and they should not be underestimated, but you also have to at least mention Michael Piller when discussing The Next Generation's tonal shift in season three.
True, Piller was the man when it came to revamping TNG. However, it should be noted that Berman put the guy in charge and Roddenberry probably would have frowned at the direction of TNG under Piller's tenure.
I'm not aware of the sage you refer to, but didn't Tyler compose Children of Dune before his Trek work? I think that score has gotten him a certain amount of notice (a portion was used in the recent Indiana Jones 4 trailer, for example).
He did, but CoD was released during ENT's second season. I don't know if that overlapped or proceeded his time on the show.
