I absolutely love it. For the first time in a long time, I have no idea where a show is going with their story line and I love it. I've called some minor things, (ok one major one but no spoilers), but I still don't know how it will apply to the overall plot.
The only complaints I've heard are that it's "too slow", and yes, it does take more than an 8 second attention span to watch. And that it's just weird. And yes, it's sci-fi with a whole fuckton of moral ambiguity. That shit is indeed weird.
