They do present information in an entertainment format, but I don't see that as a bad thing. Cody & Katy do long and deep dives on subjects that might seem rather dry without the jokes and comments interspersed throughout. I think this makes it more, not less, accessible. The important thing to me is that their information is well-sourced and cited, and it is, (links and sources are available under each youtube video.)
I feel like we could use someone to fill the void left by Daily Show era Jon Stewart, as his tone and demeanor has changed a lot in his new show. He seems to be doing more of a serious presentation these days based on what I've seen of The Problem with Jon Stewart.
