I've been watching them on DVD again, for the first time in 18 months or so. This seems to be the right interval, as the episodes are no longer quite as fresh in the mind.
They still have the same feel-good factor as they always did, though. :)
PS, are there any of the old regulars, besides myself, still lurking here? Our old friend Ouroboros posted on uk.media.tv.misc a few days back, BTW.
