There's something about the TNG theme (played during the opening credits) that seems unique and special to my ear. But I don't know about music and orchestral production to make sense of it.
It sounds to me like the mix or maybe arrangement is somewhat unusual, even compared to other TNG era star trek themes. It seems to have a brightness and sheen to its tones that are almost synth like (??) But also the arrangement seems to hit some sweet sci-fi spot, like the way strings and trumpets with oboes/clarinets underneath (??) all mix together? Or is the chords that are played some where?
I don't know, but I've always thought it had a sheen and sparkle that almost sounds like star trek (or at least TNG star trek).
I saw a lot of opinions back in the day about it, and it almost seems like people were offended that they even tried to break the mold at all.
I don't actually mind Faith Of The Heart for the intro. My biggest problem with it is that its not an original song - it was written specifically for a movie that was completely unrelated to Star Trek.
I would probably appreciate it more if they wrote their own song for ENT - it could even be a country/pop song like FOTH, but it would still be a Star Trek song.
They definitely cherry picked the best bits of the song for the intro though. I like their cover more than the original.
