Three hour shows are too long. Two is enough.
From the host's point of view, it is a lot harder to fill up three hours than two. That's where a host can use "back office" help in preparing the show, and that's what Rush does, and that's what Hannity should do.
When it comes to TV, I always thought the half-hour show was much tighter and better than the hour show. Sitcoms have usually been half hour right from the beginning of TV, but dramas generally expanded to an hour in the early 60s, and the results weren't always good. What a difference between a tight half hour "Peter Gunn," versus a padded hour long "Bourbon Street Beat"!
In particular, the original "Twilight Zone" worked much better in the half hour format. The network forced them one season to go to an hour, and the writers were much against it. And you can see why -- the "Twilight Zone" usually depended on a twist ending, and you can't really build up for an hour to a twist ending. But a half hour? Perfect!
Savage evidently thinks so too.
