4) The 25th Anniversary

A whole season of ostensibly anniversary connected stories, you say? Well, sort of. “Remembrance of the Daleks” and “Silver Nemesis” were most explicitly nods to Doctor Who’s silver anniversary (you see what they did there with “Silver Nemesis” and the Cybermen, right?), classic Who’s 25th season also included the unsubtle Thatcher satire of “The Happiness Patrol” and the wonderfully silly “Greatest Show in the Galaxy.” Overall, not bad at all!
