When I was a kid, I wasn't allowed to watch this because of the violence. Now that I'm an adult (depending on who you ask), I rediscovered this little gem. I've always liked Tom Selleck, and there was a good reason he was in demand in the 80's. Some people can't get past his Magnum P.I. days, but that's only because they don't know/ care about his long list of successful movies like Quigley Down Under, 3 Men and a Baby, and Mr. Baseball.
There were obviously some parts of the movie that haven't aged well; it was visionary, not magic. They were working with the tools of the day to tell a story. Admittedly when the robots attacked, there were a few moments where I didn't have the reaction they were going for. However, if you can look past the shortcomings it's a good show.
The thing is, it predicted the problems many in IT security have only just now started getting headaches about. Ask one, if you happen to know someone in that industry, about security for IoT and what a nightmare that is. Everyone and their mother has a device on them that is open to hacking, which presents a unique problem for people charged with protection in that area.
If there was ever a movie that I would agree to having a reboot/ remake of, it would be this movie.
