Just throwing original actors in with some neat effects does not make a great movie sequel. Being an original Tron fan, I expected more. The story was lame and didn't even mesh with the original. Jeff Bridges should make better choices. he's a great actor, but this was obviously just an extra paycheck for him.
This instance of the Indiana Jones movies was really bad. The Indy character didn't have his traditonal "clued out" but still in the game attitude. The whole movie seemed like a plot by the writers and producers to carry on his name with a younger actor in order to make more money. I told myself early in the movie that I would walk out if there were aliens or spaceships, I should have listened to myself. The story was dumb.
