Alright, I guess I derailled this.
Human Target is a prime example of Fox meddling. Showrunner was replaced. Moved production to Los Angeles from Vancover (where it was cheaper to make). Fired Bear McCreary because it cost too much (which makes the prior move of the Production Unit make no sense... also Battlestar Galactica... Agents of Shield... Outlander. Dude's got a pedigree now, so it's their loss...)
And then added women to the cast because the show was seen as 'sexist', then two thirds of the plots in the second season were rescues involving those same women adding to the sexist overtone in the first place. (What to do this week? Let's make Chance rescue Pucci again!) I didn't mind Ames as much as her character was supposed to be inept as a thief learning how to be a mercenary from Guerrero. But Pucci was grating.
I had no hope for the second season. I watched to the end, but the cancellation did not surprise me at all.
I loved the first season of Sarah Connor Chronicles. But the recession went down, RL problems made TV impossible... I completely missed the second season once I got back on my feet.
