The new HBO show Westworld is based on the 1973 feature film of the same name. The movie, which was written and directed by Michael Crichton, explores the idea of a high-tech theme park that goes haywire, an idea Crichton later recycled in his much more famous Jurassic Park. The original Westworld has many fans, but film critic Theresa DeLucci says the new series is a major improvement in terms of quality. "It's an HBO show," DeLucci says in Episode 223 of the Geek's Guide to the Galaxy podcast.
