At first this show seemed like utter crap ...
Usually I stop watching as soon as dialogs and/or the action gets totally illogical, but for some reason (boredom perhaps) I kept watching past episode 2 which imho was the worst.
At episode 3 I was ambivalent and as I kept watching the show slowly sucked me in and now after E6 I'm eagerly awaiting the 2nd season. I wont go into detail about what hooked me as it might have been the evolving characters, better acting or less illogical fight scenes.
If you like me thought the show really was utter crap and couldn't make it past E2, give it a try, I think you will change your mind.
