Thanks to the NEEToes, I had the luck to watch Westworld, the 1973 movie. Then I dl'd Futureworld which is a sequel to it. Watched it as well.
They are all right, immensely different from the telly show, for they were made in the 70s. Futureworld differs from Westworld too, has different focus, they came up with new things like controlling the hosts, playing chess or boxing matches with them like some arcade game. And they added a conspiracy and mistaken identity plotline too. I think it's a step up from the first movie.
Rewatching the telly show. I forgot how awesome the first season is.
