There's another thread where some people are piling on TOS music for being too in-your-face. But if you compare the two, I much prefer TOS music and acting style to the TNG shows. Music in the mid to late 80s on TV was pretty terrible across the board, because it was then that synths started to supplant acoustic instruments, and it resulted in stuff that sounded more at home to the intro of a Sega Genesis game than a TV show about space exploration.
And a ton of '80s films--even many of the better ones----have that synonymous beat-style music which makes it sound like it was done by the exact same person. Speaking of the in-your-face issue, Roger Ebert once said a great film score shouldn't call attention to itself. And Jerry Goldsmith once said that was the dumbest thing he had ever heard in all his years of composing.
