WHAT IT'S ABOUT Westworld is a theme park where the very wealthy go to indulge their fantasies, which are either violent, sexual or both. The theme is the Wild West, and as far as patrons are concerned, when they step off that train, they step off into another century. The so-called "hosts" who inhabit this world are perfect cyborgs, made in a secret location, and programmed by Bernard Lowe (Jeffrey Wright).
