The show now is heartwarming, but not really funny. But a worse show is "The Parent 'Hood", which so obviously wants to invoke the "positive role model" stance of "Cosby" that it is even less funny. Even in first-run, it wasn't good. It is such a third-rate, WB knockoff. It makes that "Charlie and Company" that CBS did look brilliant in comparison.
This is off topic, and there's no Parenthood thread (nor should there be), but I have a friend who was a writer/producer on the show the second season who HATED writing for the show (although he was happy as hell to have a gig) because no matter what he and his writing partner wrote, Townsend and the producers would try to stick a fucking messagase (and a corny "after-school" message at that) into the script even if it didn't really make sense in the script. He tried desperately to get them to be a little edgier but Townsend wanted corny scripts with messages to kids.
At least with Cosby, you know he did it because that's really who he is (he's an older raised waaay back in the day when they did that and the viewing audience expected it). But I agree that Townsend was a reeally bad knock-off and my friend (while respecting Townsend for his abilities) couldn't stand writing for him.
