Loved Enterprise, even though Archer was probably the worst ST Captain ever. His pacing back and forth while talking on-screen with enemies, and generally snippy attitude made me want to throw a brick at the TV at times. I was almost hoping that he'd pop out of there Quantum Leap-style when Dean Stockwell showed up.
Seriously though, I don't think Enterprise fans are more or less likely to have liked the new movies. Good writing makes and keeps fans and people are only loyal as long as what they're seeing is quality and compelling. Perhaps it's because Enterprise was the most recent ST show that many of the younger fans will remember and relate with both Enterprise and the new movies.
