I like Jonny Hart. I like Dilbert. The rest are political and make no attempt at humor, as far as I can see.
Dilbert is just wonderful, even if it's declined as Scott Adams has moved further from the workplace (for the first half-decade or so, he was working and writing the comic).
My favorite set is where Dogbert becomes a radio talk show host to promote his, "unique conservative viewpoint that people are basically idiots who deserve to be mocked" which, I think, just about sums it all up.
I'll give "Boondocks" less than a season before it's yanked from Cartoon Network. And any other group that tries to pick the show up.
This could occur due to indiference, boycott or large E-Mail and/or Letter Campaign.
Jack.
