Enterprise was a good show, too bad it was cancelled so early. Season 1 was different from the Trek I knew before, but it didn't take long to like it, and there were some really great episodes in the first two seasons. "Carbon Creek" will forever remain my favorite ENT episode. 
Season 3 was amazing. I loved the whole Xindi-storyline, though, now that I know what happened, it can get boring when you re-watch it, because the whole "what are they up to, who are they" mystery is gone. But still, it's a really good season, with similarly good episodes.
And season 4... what a joyfest. Except for that little thing they called "series finale"... *g*
If only there had been a season 5. Would have loved to see where the show was going after season 4. I heard rumors about a two- or more-parter in the Mirror Universe... THAT would have been a blast!
