Season 4 clears the ground for the Season 5 of the as-of-now-three-seasons-too-many TV saga. The creators' blackmail by cliff-hanger is unlikely to be effective. Season 5 may never come.
In the Westworld, someone gets shot in the face with greater frequency than a new Subaru rolls off an assembly line at the Subaru plant in Indiana (every 34.5 seconds). In contrast to the good people of Indiana, though, the creators of the series do not seem to like humanity very much. Their dislike is not so intense as to portray an encounter of lips with a cigarette but sufficient to justify gratuitous piercing, poking, punching, snapping, and shooting of the seemingly disposable bodies of humans and robots alike. No memorable line of dialogue, not a smitch of directorial talent is wasted on these disposable shells of creatures.
