Yul Brynner's stint as a robot is a tribute to the spirit of relentless pursuit - no matter what the guys try, they can't get away from the abused and "fed-up" robot. Singlemindedness of purpose leading to some "out-of-the-box" thinking allows our heroes to conclude with a happy ending. Fun is had at the expense of some really obnoxious people who "get what they deserve" in most cases. It all wraps up and allows for the sequel "Futureworld" later. You almost cheer for the wrong people, but I'm sure that's intended. Easily believeable and a good watch.
