In my opinion, Season 2 is a great improvement over Season 1. The whole production has really been tuned-up this time. Scotty brings a lot to the show, with the cars, the cave, and his seeming immunity to the camera. The quality of the inventions is way up. The little computer-segments describing the inventions are really good. The idea of following a successful invention all the way to the presentation to a manufacturer is extremely satisfying. I actually found myself getting a little choked-up when the Dus-T got accepted.
The most welcome change: The "suspense-pause" has been cut in half.
