The show starts out slow and builds you in. It just doens't throw you into the action and expect you to follow along. I especially love the 'dumming it down' for the science explinations. If they had that in my High School I might have actually enjoyed it a lot more. The writers have made us interested in the characters while not always giving everything away at once.
I also like that once the show was picked up somethings changed. I didn't like the character of Dr. King. He seemed out of place. It also nice that GD was given a face lift too in future episodes this layout made it look more like a crash test dummy testing facility then a state of the art science lab.
