Re: I'm touched by the weirdness of this request...
Never liked the TV adaptations. No-one has found a good way of doing footnotes on TV really, nor of the linguistic punning that Pratchett excelled at.
I agree, to some extent, and I was particularly unhappy with Sky's adaptation of TCOM, but that was as much about the casting, David Jason was all wrong as Rincewind.
However, I reckon that in some ways Good Omens lends itself more to TV adaptation than perhaps Terry's mainstream works do.
Added to that, of course, is that Neil Gaiman is writing the screenplay, so is unlikely to stuff it up as much as they did with some of the others.
