I don't get BBC America so have not seen any original show that the US has copied. That leaves me to enjoy or not enjoy without prejudice. I really like this show. At first the actress that plays Sally just wasn't connecting with me but I've warmed up to her. I did guess right from the first episode that her boyfriend had something to do with her death. I can't wait to see him get his comeuppance.
The guy who plays Bishop does well with bad guy roles. I didn't like his character on Lost and I don't like his character here, although he did show a soft side when he was in the relationship with the nurse.
I'm glad the female vamp is gone. I didn't like her at all but did feel badly for her when she asked Aiden to kill her and I understood her reasons.
I can't wait to see the upcoming war!
