Unknown Hinson, who IS the de facto voice of character Early Cuyler - the anti-hero of the show, will sorely be missed.
Yes, Adult Swim could have jumped into a cold opening of Early's offscreen death and introduced a completely new character that could have lasted for years, but somebody decided to replace him with Tracy Morgan as a lame attempt in making a short-lived/one-season political statement.
If Adult Swim and Hinson ultimately could not reconcile, they should have just canceled the show outright. Two tentacles/thumbs down.
