The original Tron was pretty groundbreaking as a movie released in 1982, at least from the visual perspective.
It spawned a bunch of derivative works - the animated show Reboot, the Matrix franchise, games like the CCG "Netrunner", books like Neuromancer and Ready Player One.
Nevermind all the technical hurdles they had to accomplish in order to generate these effects. No way you get to Toy Story or the Marvel franchises without the entry-level effort of Information International, Inc. or Mathematical Applications Group.
Surface level, sure. It was your standard "Computers Ate My Dad" silly Disney story. But it mainlined a certain flavor of SciFi/Fantasy and popularized animation techniques that have matured substantially since then.
