Doctor Who: The Doctor's Regeneration Episodes Ranked Worst To Best

Thank the Time Lord we now have the technology to binge-watch this 10-part epic. It was originally broadcast over two-and-a-half-months back in 1969, so a big shout out to those who stayed the course.

Terence Dick and Malcolm Hulke's expansive script is packed full of tension, action, grown-up themes and mystery. There's a brilliance in their simplicity of incorporating the everyday strangeness of mist between the different war zones. Though the middle episodes aren't necessarily wasted, the neverending capture-process-sentence-to-death dance does become slightly tiresome. Then again, that is war games for you.

Just like in video games, there's various boss battles the Doctor has to contend with. Noel Coleman provides a physically imposing and menacing presence as General Smythe. Dr. Evil pops up and does a great impression of Sheriff J.W. Pepper. Edward Brayshaw camps it up wonderfully as the the War Chief, complete with fetching Ming the Merciless facial hair. And the Security Chief sounds like a naughty K9. But nothing can compare with the sound of the Time Lords' approach on an eerily howling wind.

Patrick Troughton displays the full range of the Doctor with boyish energy and enthusiasm. The Doctor we've all come to know and love. He's charming to his companions and silver tongued to the enemy. Shows practical ingenuity throughout, especially with fridge magnets. He can turn on a sixpence: raging against the Time Lords "of failing to use your great powers to help those in need!"

Goodbye cosmic hobo. Hello..: after bidding a fond farewell to Jamie and Zoe (the quick glance back from her is quietly heartbreaking), the Doctor is forced into changing Bohemian Rhapsody-style. Let's hope they didn't choose one of those ghastly sketches...
