Working from the oral history in The Five Year Mission: The next 25 years, this is a fascinating deep dive that answers the question “How did a recycled cover of a 1998 song written for Rod Stewart, ‘Where My Heart Will Take Me’ aka ‘Faith of the Heart’ become the title music for Enterprise?”
Also, after resisting melodic scoring in all the 90s shows, it turns out this was the music Rick Berman liked?!!
“…I, for one, can tell you that I thought it was a great opening and I’m not alone in that. I don’t think I’m in the majority, but I’m not alone."
And it seems the song does have its own subniche of supporters who share Berman’s view. (But not I.)
After Roddenberry and his wife passed there was no one to reinforce the ideals that drove Trek.
DS9 was arguably anti-Trek, or at least seriously questioned the idea of the Federation as a force for only good in the realpolitik of the Alpha Quadrant.
I feel like the problem with Voyager and Enterprise was more that the writing wasn’t as good.
