Quick Review - Tron: Legacy

Like remakes, sequels can be an issue if I haven't seen the prior edition. In the case of "Tron" and its sequel,  "Tron: Legacy," there was a 28-year gap between films so I figured that they would explain enough about what happened in the first one to get people up to speed -- especially since "Tron" never caught on the way a film like "Star Wars" and its sequels did. And it did explain things. I still don't quite understand it all, though. Programs and Users and ISOs and The Grid and all of that. I was amused when Sam Flynn (Garrett Hedlund), son of the protagonist in the original (Jeff Bridges, whose younger self is digitized to appear as Clu, or "Codified Likeness Utility," as well as the now-older Kevin Flynn), went to his father's old arcade to check out something related to his disappearance (twenty years earlier), and while stumbling upon the computer lab and machinery that transported Kevin, and then Sam, onto The Grid, turned on the old jukebox. What amused me: the old music playing in the old jukebox -- Journey's "Separate Ways and especially Eurythmics' "Sweet Dreams (Are Made Of This)." The rest of it confused me at times, though it isn't a complete bore. It certainly looked great, though -- except when this happened. My grade: B-minus.
