Well, they're about 10-15 yrs late, IMHO. The show lost its way quite awhile ago. I was a big fan for the first 15-20 yrs, and, being an NPR fan, I'd go out of my way to flip it on - not just in drive time or trips to the grocery store.
The show clearly revolved tightly around Keillor and his shtick. Somewhere ...years before Altman's movie, it was losing its creative juices.
It's perhaps nitpicking, but radio people that constantly inhale loudly through their nose are a major nuisance. Many people have noted it and found it annoying (b'sides me).
However, after Keillor made the hugest gaff when he was critical and xenophobic around giving Xmas back to Christians (critical of Irving Berlin and outsider's songs about Xmas) and giving Christmas back, he lost many fans of the show. What a putz! Let me see if I can find a link...
Anyhow, if they can change the brand and de-Keillor-ize it, and still keep an audience, I'll be shocked. You can kiss his Prairie-home-ass g'bye.
Wishing the best of luck to Thile:
