I'm in mid-season one right now... just finished "Drop Dead Gorgeous", so i'm in the middle of season one. I'm so pissed off at FOX, so so pissed. In just a few episodes Tru Calling has become one of my favourite shows, and I didn't expect that at all.
It's just so fun, witty, and beautiful. The typical "older sister getting the brother out of trouble" theme, yet so fresh. I never get tired of Harrison's antics. Tru is great too... so much better Buffy, and a true heroine, without any real superpowers and making a difference. Seeing Eliza's new character, I just realized what a slutty and shallow character Faith was. Totally below her. She truly shines here, and I sense she is only going to get better. Lindsey's awesome, very cute, I love how the different days show her insecurities and contradictions. The characters are so alive in this show... you really sense that you are getting to know them. Davis is so funny too - "I can't work on alive people, they freak me out!" -

And they are not vampires, they are not slayers, they are regular people . That's what I love.
The story is so touching, and not only the overall arc. The episode about the father trying to find a heart for her daughter really got to me. I dunno if I'm crazy, but Tru's character, in reaching out to the people she helped, seemed to reach out to me as the audience.
Well, as i said, i'm in the mid-season, and i'm told some changes are gonna happen in a little while and it's gonna get much better. Maybe i'll report my thoughts when I get to the finale.
Anyways: FOX, seriously, F-U. You always cancel the best shows. Angel, and now Tru. Die.
