It starts of with a CGI young Jeff Bridges talking to his son about his tron world. The next day Jeff never comes back from work. When the kid is 27 he learns how to get to the tron world where he reunites with his father. They are trying to get to a portal to get home before clue (the evil guy in the movie because every movie needs an problem.) I wish the movie wasn’t called Tron: legacy because the tron charecter only says one line in whole entire movie. The 3D was very subtle which is weird since its a tron movie. But I cant stand when 3D is to much so I didn’t really mind.
