It's hard not to compare this show to Humans, considering they come out at around the same time and are ostensibly about the same thing, and watching the two shows together just makes Westworld seem ponderous and needlessly obtuse. You have scenes where people just explain shit to each other, revealing plot details that aren't exactly hard to infer or guess at to the people who don't want to think and just want everything spoon fed to them. This of course makes all the "mysteries" and whatnot feel like a waste of time as well, because there is nothing really mysterious about them. It's like the worst aspects of Lost combined with the worst aspects of Game of Thrones.
It doesn't help that the presumed ethics of having sentient murder/sexbots doesn't really go anywhere, particularly when the show is so insular and just focused on this park that only rich people can afford to go to.
I suppose it worked as a Western if nothing else?
