Bringing back the most successful modern Doctor and companion, adapting a classic Who comic, bringing back Mel and the Toymaker in a multi-Doctor story, referencing Sabalom Glitz, Logopolis, Mavic Chen and Adric, not to mention Tales of the TARDIS ... nope, not celebrating Doctor Who at all.

Yes. It's easy to forget amid all the UNIT and bigeneration stuff how much of The Giggle is a proper direct sequel to The Celestial Toymaker, with the corridors, the sinister childhood imagery, the banal games made significant, humans being turned into playthings.
