Haven't been up on the boards so much lately, but wow, I'm shocked that this isn't a super bumpin' thread. Westworld is pretty great. A television show hasn't engaged me this much since True Detective (season one).
I would say, we should start posting our theories, though at this point a lot of the cards have been turned (or strongly hinted at), and we should probably just enjoy the ride for the last couple of eps. Great series.
