Night Of The Living Geeks

Well, folks, The Power of Three. Is it a reference to the strength of the Doctor plus his companions? Is it a reference to the "cubed" nature of our villains tools? Is it just something that sounded good in Chibnall's head as he wrote a rather glossed over story full of exceptional amounts of handwavium? We're not really sure and, as such, that causes this story to land rather awkwardly. Though it does have some good moments (heartwarming ones as well as the introduction of Kate Stewart), we kind of feel a bit meh about this adventure.
