Well, go and watch the 1st three seasons for character development.
Just got done with CoE again - hands down the best of TW. I read there was a huge brouhaha over Ianto's demise, but whatever, I loved CoE... that ending has to be one of the most dramatic endings in TV history...
Miracle Day, well, I thought in parts was excellent, but I wish it had been Britain-based instead of U.S. based... I didn't like Rex or Esther, but I loved Jilly Kitzinger (not just because she's played by the very hot and amazing Lauren Ambrose
of Six Feet Under fame).
As for people whining about Jack's "gayness" get over it, seriously. The character is pansexual, yet nobody complains when he loves women, only when he loves men.
The main character is a straight woman and her husband and their newborn baby are always with her, but hey, we have to ensure that no gay or bi male character gets to express their sexuality or love on a tv show... Nobody complained that Rex and Vera were having pretty graphic sex, yet people wrote to the BBC complaining about Jack's m/m sex scenes. LOL.... and then to hide behind "oh I don't mind *gayness* I just don't want it shoved in my face"... riiiight... 'cause straightness ain't shoved in our faces all the time, but that's a-ok, right?
Whatever... just enjoy some Jack Harkness.
