DON'T MISS: "Westworld" – It's payback time as the dark, mind-bending thriller returns for its highly anticipated second season. When we last left the futuristic theme park, its enslaved "hosts" had learned they weren't actually humans, but androids programmed to follow a script and serve at the pleasure of their flesh-and-bone guests. Cue the robot rebellion. As the saga resumes, the androids, including Dolores (Evan Rachel Wood) and Maeve (Thandie Newton), have revenge on their minds. Better not cross them. (9 p.m. Sunday, HBO).
