A concept story that grows on you
If memory serves, this episode is named after an Escher drawing, where stairs lead, circularly, only to themselves, and neither up nor down. In the episode, this idea is toyed with and played out as if it were a physical reality. The laid-back approach to the story, the Doctor's inability to recover his own identity (Who?), and the pleasure of watching the absurd physics unfold make this a worthy story and beginning to Peter Davison's tenure as the fifth Doctor.
