Doctor Who episode 677: Remembrance of the Daleks – Part Four (26/10/1988)
‘I can do anything I like.’ It features the Doctor’s most complete victory over the Daleks since 1967, the most spectacular (and toy-free) Dalek-on-Dalek battle (including the hugely memorable Special Weapons Dalek), and some of the best practical effects the show’s ever done (the landing of a full-size Dalek shuttle). However, it ends at a funeral and a doubtful Doctor unable to reassure Ace that they’ve done good. This makes some sense of the obscure title: Remembrance Day comes with the implication “never again”, and of terrible and unconscionable sacrifices made for future generations to live in peace.
