I've finished season 1 and I thought it was dull and boring.
I'm half way though season 2 and I think that it's not just boring but also terrible writing. The show has its moments (I liked Adam and the Owen saga wasn't bad) but I can't in anyway recommend this show to anyone.
Here are the 5 what main problem I think are with the show:
#1 The characters are unlikable. Besides Toshiko and you could argue Ianto the characters are completely self absorbed, uninteresting, mean spirited and have little character development to care about them. At least we saw some development with Owen but its still so very little after a season and a half.
#2 They took everything that was likable about Jack, out of Jack. He was fun, exciting and funny when on Doctor Who but since Torchwood he's been stripped of any and all of those characteristics until POP he shows up in Doctor Who again and is back to being fun to watch. Not only that but he's sooooo distant he's almost a background character.
#3 Over the top Sexuality and specifically Bisexuality. Seriously we get it, everyone on the f**king show is bisexual. Yaaay you've established yourself as the first bisexual sci-fi series great...can we please move on now. It doesn't have to define your damn show!
#4 NOT ENOUGH REAL SCI-FI!!!!!
#5 Overall poor writing. All of these problems with the show come down to it AND the stories are predominantly shit.
I WANT to like this show, I was really excited about the prospects of an adult oriented Doctor Who spin off until I sat through most of it. The show is brutal. In my opinion the only way for this show to be saved from the low class sci-fi its found itself in is to scrap all the writers and give a new group full range to do what they want with the show with the message "Make this show fun and an actual sci fi".
