Not such a big fan of this show although I am a massive fan of John Christopher, author of the original books on which the BBC TV series was based. Good old Aunty Beeb only managed to get two thirds of the way through the trilogy before giving it up as a bad dull thing. They should probably have another crack at it now that technology is more up to the job but then again if it turned out to be only half as witless as their last attempt at Day of the Triffids, then they perhaps shouldn't bother.
