I like this show. I particularly liked season one. Yes the mechanical dogs were a bit quirky and you could question how they seemed able to access all areas, but I wouldn't want one of them chasing me. Also I was pleased that it wasn't just a rehash of the original story.
But the direction of season two worries me. Time travel, really?! So many holes. (As others have noted) why would you go back in time to kill a man who creates a virus, if the only reason he creates the virus is because you went back in time? In fact, if you never went back in time even the thought of going back in time would never have arisen. Also, if you go back into your own historical timeline and wipe out the majority of the population, doesn't that bring your own existence into question? Every time an invader kills someone, ten invaders should cease to exist.
Hopefully the writers know more than me and have a great storyline out of this mess.
