We all knew that they would be criticized, I mean its a satiric show, however any type of attention is good attention. I am not too familiar with the Colbert fan base, but hopefully it will convince people to do research of their own.
I think it's mixed. Other side thinks he is real thing and other one gets the satire...
I think the not too positive way of advertising it is the right way. Get's people interested, but don't create new craze...
