I recorded this and watched it today. I liked it well enough to start taping the series. Katey Sagel and Ron Perlman really lead the rest of the cast, who are fun to watch as well. It seems gritty as the other FX dramas.
Yeah, part of Dwight's appeal is trying together all the craziness of his homelife from the little clues on the show. If we saw Mose all the time it wouldn't have the same impact as a random cameo of him doing something odd and backwood.
