Agree with everything you said. Larry Bud was greatness.
Remember how funny Chris Elliot was? The mistake with Dave was changing his show. They gussied it all up, tried to make a big deal out of it, which totally blew the whole concept. Part of what made it so fun was that it was simple, low budget, and silly. The show itself was a joke, and that was part of the appeal. He started taking himself seriously. That was the downfall.
