I like the theme song from Enterprise
I honestly don't understand people dissing the song, in many cases it seems to be simply disliking it from being different from the other shows, which makes no sense.
Because it sounds like a cheesy 80's hair band ballad. Now that's fine if you dig that kind of music, but I do not. Also, I do not consider that kind of music to be "timeless", thus not fitting into a show about the future.
Honestly, my dislike for the song lessened once I began to appreciate the show, although I still far more prefer the more classical opening themes of the other shows. Just more appropriate in my opinion.
