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.
Re-arranged for a smaller orchestra, and more energetic (most noticeable in the percussion)
