I was really looking forward to the first series. Not having read the books I had no preconceptions and was very interested in the premise.
For reasons I don't fully understand myself, the TV show totally failed to hold my interest. I don't know why, but when faced with watching an episode of AC I just thought my time would be better spent elsewhere.
What makes this odd is that I am a real sci-fi enthusiast, so it should have been right up my street. Needless to say, series 2 has not been explored.
By contrast I have been watching Westworld, where there is some overlapping premise, and I have been totally engrossed by it.
No such thing as a "sure" thing, I guess....
