Watching HBO Westworld too - Liking the modern twists on the original premise. - My ( 80 year old ) father in law is a huge sci-fi and western buff, and was really excited when i was describing the westworld re-boot to him. However I think that sadly there is just too much cursing in the TV show, particularly from that young story writer guy who cannot help but 'F' in every sentence. My mother in law wouldn't stomach it because it IS un-necessary to the story.
Coincidentally watched the Movie sequel to the original Westworld ( 1973 ) last night: FUTUREWORLD ( 1976 ). Different idea that time, and the hero is randomly chased by samurai around some underground tunnels instead of a cowboy. A shameless cash-in, and although fun it's not very good to be honest.
Still, at least we can watch these things for free online nowadays without wasting time and money on rentals.
