16 The Barchester Chronicles (1982)
there's a scene in peep show where super hans and jeremy are coming from a night on drugs and they decide to watch the barchester chronicles as some kind of unchallenging and ultimately calm piece of old-fashioned 'brown' television that won't freak them out. i took this as a tacit endorsement and looked the show up immediately.
