Tron legacy wasn't that good anyway.
The story goes like this, apparently it was the evil clone of
his dad who lured the lead into tron world, so he unwillingly had
to play that light cycle game, then a girl came to his rescue,
apparently the girl knows his dad, so dad and him reunite, and
their main objective now is to get out of tron world coz that evil
clone wants to get out and rule the real world. So obviously the
dad died, the bad guy loses, and the good guy gets out with the
girl. The end.
