Fallon excels with the skits and ones that allow him to break. Not really the monologues.Yeah, i'm slightly surprised too, but I also think maybe they're betting that his ratings will rebound with a new administration in place, as maybe they're hoping late-night won't be so politically charged. Fallon not playing the politics angle/not being good at it is a big part of what led to his ratings decrease.
Conversely, I found someone like Colbert irritating as a late night host, but loved him on Colbert Report
And then there's Jimmy Kimmel who just comes out crying every night which makes everyone feel akward
So yeah...Fallon is the best to have a ride of his own and be a theme park attraction
