Meh. I have no emotional investment here but I enjoyed Stewart and the show at times. Others times not so much. It was never must-see TV for me.
Sucks that the new guy isn't going to be given a fair shake. I'd imagine he's only going to be hosting for 2-4 years regardless, before moving to bigger/better things; that dude's upward career trajectory mirrors that of a handsome white man with a C average. Stewart didn't waltz into the job as a good host, it took him awhile. But you already know people are going to dismiss this dude after an episode, or a week, or a month, etc.
