Funny, I feel this way about DS9 but I know everyone else in the world loves it; that's cool. I enjoy "Enterprise" and if I'm honest; it is my second favorite Trek after TOS (although I do enjoy TNG & Voyager).
Though the really, REALLY funny thing is that those who proclaim to like "Enterprise" disqualify their opinions from serious consideration by virtue of their self-evident lack of discernment. It's sort of like having a person who likes the smell of poo help you pick out your perfume/cologne.
I kid. I kid.
