"Tron: Legacy" is a sequel to the 1982 original and brings back Oscar-winner Jeff Bridges as the feature character Kevin Flynn. The story focuses on Flynn's son Sam (Garrett Hudlund, probably best known as Don Billingsley on TV's "Friday Night Lights" and Murtagh in 2006's "Eragon") who was orphaned 20 years ago (actually 28 years ago, but for the purpose of having a young new hero that comes out to 20 in movie years) when his dad was trapped inside of a software program.

Sam, who grew up as an orphan, initially believes that his dad ran away and ignores his duties as principal shareholder of his dad's company Encom and instead becomes bitter and rebellious. Kevin's friend Alan (once again played by Bruce Boxleitner) receives a message from Kevin's old arcade. A skeptical Sam goes to check it out and discovers a secret room where a computer is hidden. And we're off. Sam ends up in a computerized world known as the Grid.

While the journey is riddled with CGI effects, including Jeff Bridges as a younger version of himself, the fact is that the special effects in "Tron: Legacy" don't have the same impact as they did nearly 30 years ago. Back then it was revolutionary in a world that was absorbed in video games such as Pac Man. In today's 3D-obsessed, special effects over plot world it doesn't seem so fresh.

Sam eventually ends up in the Grid and is reunited with a younger version of his dad, actually a look-alike created by the computer known as Clu. Later on a weathered present day Jeff Bridges emerges to stop the evil digital doppelganger. In a CGI-created flashback we see a younger Kevin leaving his young son all those years ago. Eventually Sam and the real Kevin reconcile their differences and work together to battle Clu.

Virtual creation Quorra (Olivia Wilde) joins Sam and Kevin in their quest to stop Clu. There is some possible romantic attraction between the two, which is never fully explored (which may be a good thing since she is basically an Avatar). Garrett Hedlund somewhat resembles Jeff Bridges, making the two more believable as father and son. Bruce Boxleitner, Olivia Wilde and Michael Sheen as Zuse bring some much-needed human emotions in a sea of special effects and action sequences.

"Tron: Legacy" is full of bells and whistles, but lacks much of a substantial plot. While it is satisfying to see what became of Kevin Flynn after all these years, there really isn't much more to this sequel.
