If it had anyone but Karl Urban I wouldn't have been impressed, as it does feel like it's retreading lots of previous series (Blade Runner of course, but also Caprica, of which it shares filming locations and actors).
But it did hold my attention, it shows signs of some original near future tech ideas and it did have a human warmth to it that tosh like Agents of Shield couldn't dream of. It's kind of scifi for the masses, I guess. I'm looking forward to seeing where it goes, particularly once this first story concludes.
Must admit the good cop/black cop thing made me feel a bit uneasy, but to be fair, Urban's character treats all the androids like shit.
