10 'So Bad It's Good' Classic Doctor Who Stories

Evil giant slugs, terrible twins, and a psychotic Doctor all go hand-in-hand to create by far the worst, funniest, and somehow most entertaining story in all of classic Doctor Who.

1984's The Twin Dilemma was the public's first glimpse at Colin Baker's Doctor. The show's producers were set on making Baker a much darker Doctor who suffers intensely from post-regeneration trauma. For better or worse, this gave us a Doctor who constantly attacks and complains at his companion Peri, before strangling her in a scene so poorly executed that it wouldn't look out-of-place in a Monty Python sketch.

The Twin Dilemma's plot (if you can even call it that) centres around the Doctor saving two genius twins from an evil giant slug on a desolated planet covered in slug trails. The Doctor then destroys the slug, Mestor, in a mind-bending scene involving Mestor possessing the body of another Time Lord, with this Time Lord forcibly regenerating and killing Mestor in the process.

The Twin Dilemma is, without a doubt, the most hilarious, badly thought-out, terribly produced, and yet most wildly-entertaining story in the entire run of classic Doctor Who. It also ends with one of the most famous lines in the show's history, which sums up perfectly the tenure of Colin Baker: "I am the Doctor... whether you like it or not."
