DTM is a mostly forgotten show, how come?
DTM clearly has been mostly forgotten by time in the popular memory.
IMO that is because of Dennis' ugly & stupid costume that he never changes, and because of his freakish haircut. He is supposed to be a normal boy, but those things make him look like a silly & unrealistic caricature akin to charlie chaplin's "Little Tramp" caricature or something like that. I think if they simply chose to let Dennis look normal instead, this show would have not become lost to the large extent that it has been.
Why do you think that DTM has been mostly forgotten?
