Brett Erlich and Ellen Fox review "Tron: Legacy," the follow-up to the 1982 cult favorite that starred Jeff Bridges as a man trapped inside a software program. Bridges is back playing several versions of his prior role (in the present, in the past and as a computer avatar) while Garrett Hedlund plays his son, who enters the virtual world in search of the father he never knew. If that sounds confusing, well, it is. But can cool visuals and pulsing music (by Daft Punk) save the day? infoMania is a half-hour satirical news show that airs Thursdays at 11/10c on Current TV.
