You are entitled to your opinion but try to keep in mind that you are describing three milestones in an evolutionary process. These are performers who are in every sense building off of the work of the one before them. You are outlining the construction of a machine that began with Stewert in 1999, Colbert in 2005 and then Oliver in 2014. A machine with elements from 1999 that don't work as well anymore and elements from 2014 that wouldn't have fit in 1999.
