Bishop Twankey, Yaz and Professor Yaffle go on an extended vacation, I mean holiday, looking for something unknown to stimulate their imagination, passing through a number of nations, with plenty a frustration, irritation, futility and aberration, especially for the viewer of a certain persuasion (you know who you are), but generally a pointless piece of timewasting. The Angels deliver the Doctor to wherever it is they're meant to deliver her, like stone chauffeurs, doing a transfer, a bit of a blur, did she leave a tip? Don't treat your audience like kids perhaps, this is a show for grown up men. There's some chit chat with mam and, for those with middle age and male characteristics, more hyperventilating and high blood pressure - stress, can't cope with change, why can't we go back to the good old days, alas they were awful that's why, those days not Doctor Who. The engaged couple provide more un-thrilling padding out to make it to an hour, bravo, and the most irrelevant serpent that ever slithered wastes even more time. All we need now is a turtle head with a chocolate fetish!
