Of it being very British humour, though, I will agree.. in the sense that any night of the week I can turn on the tv and see something homegrown and billed as comedy that makes me go "OH GOSH, shut up, do something new". Much like this did.
Actually it was one of the first Elseworlds I read, and it was a massive disappointment to me. I was in a bookshop and had just gone through Red Son. The comparison was not kind.
