This was a really fun episode. First of all, having Christopher Lloyd play an aging rock star is wonderful. He is a superb actor. We see him sometimes as being on the lunatic fringe when in reality he is a producer, director, and a great character actor. The explanation the observer makes to Walter is really amazing and the corrections needed make sense. Walter needs to realize that too much of what he does goes untested. He is also careless with dangerous substances lying around his lab. Mostly, this is a great transitional piece which is necessary. Walter is so fearful and so guilt ridden and we can't have this be a constant for much of the time. He is being tested by the Observers.
