Pretty much every episode of Doctor Who is an action sci-fi film.
How is An Unearthly Child sci-fi action? Or The Daleks? Or the Edge of Destruction? The Aztecs? City of Death? Warrior's Gate?
Of the entire 26 seasons of the original run, only some of the UNIT stories come close to being considered action. And they're hardly frantic in pacing, tending to be slow, stagey 6-parters.
Did the previous episode, The Name of The Doctor, even have
any action at all? No, and it didn't need to. Was fucking awesome regardless. Give me that over an Abrams/Orci/Kurtzman burger of blandness any day
one episode this season was called "Dinosaurs on a Spaceship!"
When Doctor Who is fast-paced adventure, it is quirky and offbeat. There's a very large difference between Dinosaurs on a Spaceship and bloody Star Trek Into Darkness.
