Barley was well weapon. But I'm not sure Morris would want to do another series anyway, he seems to like to move onto new projects rather than rehashing existing ones.
Acording to "internet reports" Charlie Brooker and Chris Morris were set to write another series but fell out, Brooker wanted Dan (Ashcroft) to live on the roof of Nathan's studio, Morris wasn't happy, yadda, yadda, surley a second series would be a good idea, at the time, when it was first broadcasted, it didn't half get some stick, but now it's turned into a cult like DarkPlace. Bring it back, you know it makes sense! Yeah?
Ive said it before, one off special maybe an hour long to tie up all the loose ends, but its not up to me.. anyway maybe its just fine the way it was left.
