At first, I hated Captain Archer with a passion, but I loved the guy who played Tripp. As time went on and they actually remembered they were in the Star Trek universe, the stories got better. I warmed to Archer over time.
I still hate the theme song with an abidiing passion.
Of course when they did the whole Mirror/mirror universe episode, with full orchestral score, I choked on my pot-roast! LOL
Figures it started to kick butt story wise, so they killed it.
