Just watched the first two episodes. All I have to say is... meh. :\
Honestly? I was expecting something better. I was expecting something that could knock my socks off in terms of what a scifi show could achieve. Yet all we got was some standard MIB/X-Files copycat with a some swearing and sex mixed in.
Don't get me wrong though, I think the show is quite decent in some places. John Barrowman is pretty good as Jack Harkness, who seems to have matured from the sex-crazed conman we were introduced to in
The Lonely Child to a fine team leader (

it was quite a shocker for me to see that he can't die this time. Obviously Rose did too good a job bringing him back to life.

The rest of the cast I could take or leave. None of them really left an impression on me to even care about them.
Another thing I think is wrong with the show is that it can't seem to decide what tone it should take. Is it serious and scary? With an emphasis on the fear of the unknown much like the
X-Files was? Or is it tongue in cheek? Focusing on humor and the witty dialogue, much like
Doctor Who? Perhaps they were trying to mix both, yet couldn't quite succeed (SPOILERS
a good example of this is the scene with the Weevil SPOILERS).
Now I have grown to respect Russel T. Davies recently for his work on
Doctor Who, but lately he's just been annoying me over his boasts on how
Torchwood would be a more adult kind of scifi. In my opinion though, having a bunch of soft core sex scenes and same sex kissing on the program doesn't count for mature programming. I'm not bothered per se by such scenes, but really they come off kind of juvenile more than anything. Perhaps Mr. Davies ought to watch
Farscape and
Battlestar Galactica as examples of how to pull off mature scifi for future episodes.
Gah. Anyway, I'm ending my little rant here. I'll probably catch the rest of the episodes to see if they improve. But in all honesty? I don't think this series will capture me in the way the new
Doctor Who did.
