Let’s be concrete , Tron (the first one 1982) from a plot perspective has nothing to say .
The great idea of Tron was the animation and the visual aspect. Who can forget the motorcycle fight? Probably the most iconic moment of the movie, or the little intresting character like the one in the antenna tower? Tron is that, a terrible bad acting (Bridges far from the Lebowsky masterpiece), but an (outdated) visual experience, first in his genres.
Sequel still not watched.
