The original Tron is a bit slow and certainly dated now. But to tech geeks its prophetic in many ways. The gamers its downright scary how much it predicted….
Tron Legacy is much more mainstream. Once you get past staring at CGI young Bridges, it is a great film often overlooked. Again probably prophetic once actual AI is fully realized.
Its a beautiful film, with a great soundtrack and is quite deep on main levels if you understand the story.
