As far as I could tell in Legacy, Sam Flynn just shows up and has no reason to be any good at doing anything in the Tron universe, he just is. His father could have left his swanky cave and just done whatever it is he did, at any time ... to end the film. No rhyme or reason to anything.
Interestingly enough the author kinda describes the same problem in Ares, rules aren't clear why anything happens. It just does sometimes, except when it doesn't.
Ares isn't dong well, and Legacy did, but I kinda wonder if the emptiness of Legacy meant that anything next was dead on arrival. Fans already saw that, couldn't think of why they'd see it again if there's not much too it...
