This was a good show that I enjoyed and watched every night. Not as good as the show it replaced, but whatever they put in the Nightly Show slot (eventually) isn't going to be as good either. And, until they can come up with something, the replacement is going to be @Midnight. Which, if one show HAD to be canceled, I'd have prefered it have been this one. I watch it, but I wouldn't miss it if it were canceled.
I think they should have given it more time to find an audience. It took awhile for The Daily Show to evolve and become as popular as it is today. 4+ years according to Wikipedia, which says "The show's 2000 and 2004 election coverage, combined with a new satirical edge, helped to catapult Stewart and The Daily Show to new levels of popularity and critical respect" (1st aired in 1996).
