So after speaking to a few people over the course of the past week or so, it has come to my attention that many have not seen the supremely funny "Garth Marenghi's Darkplace". For whatever reason, the show did not gain traction with viewers in the U.K. initially. After it had already been passed over for a second series, it caught a second breath of life on this very internet that you are using, of course.
The show's premise is that its creator, Garth Marenghi, is finally getting to air the episodes of a programme that was originally taped back in the 1980's only to be deemed too extreme for audiences by Channel 4. The episodes we're seeing are being aired only because of the "worst artistic drought in broadcast history".
Much of the cast has been involved in other cult hits that have made their way to this side of the Atlantic ("The IT Crowd"--which is currently airing on IFC--and "The Mighty Boosh", for starters) before and after, and their talents are on display in all of them.
I posted a brief clip of an episode a while ago, but what follows is the first episode. To my knowledge, all the episodes are available on YouTube.
