DumbLand is comprised of 8 short episodes, all crudely animated (and I mean cruder than crude) and all about a nameless family (dimwitted psychotic father, hysterical inarticulate mother, annoying squeaky voiced kid) and their depressing (& hilarious) adventures around their home.  There is something worthwhile here, and like all great art, it gnaws at the truth of our existence and illuminates it.  All written & directed by David Lynch, all characters voiced by David Lynch (and I am assuming he drew everything too).
