I'd say that the Tron: Legacy doesn't require you to have an imagination, it just requires you to nod your head and agree to all of the stupid stuff that happens in the movie. Here's the best review I've read on Tron: Legacy. http://tronlegacyreview.wordpress.com/ It catalogs all of the significant problems with Legacy.
Sure, on the surface, this seems like a good idea. Bring the president into the 21st century with an encrypted device for communication. The problem? EVERYTHING the president does is recorded and aside from classified/top secret stuff, supposed to be available for the public record. Obama gets around this by using this encrypted device. Who's he calling, or texting on his blackberry? We'll never know. Truth is, he's the PRESIDENT, he has hundreds of people constantly following him around, assisting him. He does not need a blackberry.
