Doctor Who: Every Doctor's DEFINITIVE Episode

Not unlike the harassed junior doctors or family patriarchs he'd play in later life, Peter Davison's Fifth Doctor was often a slightly out-of-his-depth victim of circumstance. The Caves of Androzani is therefore the most fitting story of his era, because it places him in the grimmest, most impossible situation imaginable.

This is no longer the Doctor who stood by and let the Silurians and humans kill each other in Warriors of the Deep – this is a man who will go to hell and back to save a single life. Peter Davison is absolutely brilliant as a Doctor who quickly realises that his idealistic worldview is out of step with the grim realities of Androzani's corporate and military complexes.

It's often forgotten that Davison is a superb actor, who was sometimes wasted in the role of a thinly characterised Doctor. Thankfully, writer Robert Holmes finally gives him a chance to showcase the nuances of the character in a send-off that darkly defines his whole era.

Your first thought might be cricket whites and celery, but underneath all the quirks The Caves of Androzani is a true reflection of who the Fifth Doctor always was.
