Let’s get right to it, shall we? I do not like the choice that was made in this episode. Even if the disposition of Bill is another fake out that can be reset by a time machine or some questionable loophole al la Clara, what Moffat has done with this beloved companion is manipulative, cruel and pointless. This kind of nonsense happens too often and no amount of timey-whimy reset is ever going to make it okay.
Guaranteed to cause outrage, it does not matter if the audience was warned with the line “positive attitude will help with the horror to come.” I suppose Moffat wanted to outdo his predecessor, and I suppose he has because this latest example of companion abuse is arguably worse than what was done to Donna.
Without this looming meanness, this penultimate appearance of Capaldi’s Doctor would have been an intelligent and exciting episode. A massive spaceship, a shifty but hilarious Missy, an old foe and the ultimate nemesis add up to potential greatness. The masterful elements are still there but are largely overshadowed and dashed by the meaningless loss of a beloved companion (even if her condition gets reversed next week).
