I agree with Interference - I don't hate it, I just really wish it was so much better.
For me, part of the problem is that all of the leads are a pretty unlikeable bunch (including Captain Jack). The female lead, Gwen, seems quite prone to histrionics given that she was meant to have been a policewoman of some experience. (Ok, she's now experiencing situations beyond her ken, but still...)
You can have an 'adult' series without making everyone selfish, self-obsessed, arrogant and argumentative - the writers must have been to the Eastenders school of dramatic writing.
And, agreed, many of the stories so far have been quite derivative. For 'Countrycide' read 'The X-Files' episode 'Home'; for 'Greeks bearing gifts' read the 'Buffy the Vampire Slayer' episode 'Earshot'; for 'Day one' read the movie 'Species', etc. etc.
From what I read, a series two is on the cards - let's hope they improve as a good, adult-themed, Brit sci-fi series would be very welcome!
