Why haven't they made this into a series. This is better then Tim and Eric, or saul of the Mole man, combined.
The official explanation from Adult Swim was "you couldn't handle another episode". Honestly, I have absolutely no idea, because it was easily one of the best shows they ever aired along with Home Movies and The Venture Bros.
My closest guess was that the show was dropped because it was in direct competition against Metalocalypse for the same core audience (I think they were proposed around the same time), so the execs made a decision.
It's a shame, because Korgoth had so much potential and a wealth of material to draw from.
