AD isn't really like any other sitcom I've ever seen on television so all this "it would be better if..." is just conjecture anyway.

Can one of the people that say Jason Batemen's character doesn't work because he's the only normal one, give examples of other sitcoms with the same style?

For me all that matters is that I laugh out load when I watch it. The only other consideration I have with a sitcom is if it's a "Black" sitcom and the comedy is too coonish (your defnition of coon may vary).
Since AD has no Black characters that consideration is null and void.
