I have to agree with Boomerang. The last six episodes were great (Jack was in the last three), and made up for the mediocrity of the the first half of the season. I also liked Martha (she's going to guest star on Torchwood. Too bad if you don't like her

) more than Rose.
I prefer Doctor Who. Generally I just find it to have higher production values for and Torchwood seems to rely too much on the "everyone is sleeping with everyone else" angle.
