There's always gonna be plotholes in a show like this. It's about the size of the plotholes and whether or not they ruin your enjoyment.
I'm getting True Detectives vibes about this, not wrt the show quality as TD did take a noticeable dip although I still enjoyed it, but wrt to the reception (and expectations). It's all pretty similar to the first season in style, quality and execution I don't know what some of you were expecting.
First season was vague, meandering, complex, had plotholes and contrivance etc. Just like this one...
I don't get that Ford bit. Westworld is basically one big island. Meaning the hosts are contained per default and there is no destroying Delos or protecting the cradle, because even if the Delos as a company goes bankrupt over it some authority will just clean up the mess, even if they have to nuke the whole island, short of the hosts taking over the world, Westworld was sure to get wiped the moment the shot into Ford was fired.
And imho MiB is quite clearly there to play the ultimate game. If he was interested in controlling things he could simply get himself extracted and use the Delos mercenaries to achieve whatever he wants. Flying solo through the park does not make any other sense whatever way you look at it.
I'm also not convinced that he is a host. The final encounter/attempt with Delos senior seems very recent, during which he tells him that the science is still some years away and questions whether the world would be better off without him.
I'm kinda with you on this I don't think MIB is a host, although it's possible. With wrt the ultimate game tho.... Haven't for a clue what that entails. Color me intrigued...
