Sleep No More (Doctor Who)

Sleep No More is an episode from the ninth season of the revived Doctor Who series. It features Peter Capaldi as the Twelfth Doctor and Jenna Coleman as Clara Oswald.

Plot
The Doctor and Clara land on a space station in Neptune's orbit, and meet a commando team who are investigating the disappearance of the station's crew. It turns out that the crew has been transformed into monsters made out of "sleep dust", which are now out to kill any surviving humans on the station.

Why It Can't Sleep No More

 * 1) Extremely poor usage of the "found footage" visual style. Most of it just looks like a normal episode of the show but filmed at weird camera angles, and the point-of-view shots are filmed so badly that some viewers complained to the BBC that watching the episode made them feel physically ill.
 * 2) The found footage genre had been literally done to death by the time this was broadcast.
 * 3) Monsters made of "sleep dust" (the gunk in your eyes when you wake up) are not a scary concept in the slightest, no matter how the episode tries to present it.
 * 4) Clara, after being written much better for most of Season 9, suddenly goes back to constantly insulting the Doctor and believing herself to be better than his past companions.
 * 5) One of the commandos gets a big dramatic scene in which she sacrifices her life to save a colleague, only for the guy she saved to die off-screen less than a minute later, making her sacrifice totally pointless.
 * 6) Mr. Sandman, while a good song, is overused.
 * 7) Most of the story is just made up of the Doctor, Clara, and the commandos running away from the monsters, which quickly gets boring. It's not until about five minutes before the end that the Doctor thinks of an actual plan.
 * 8) Keeps cutting back to the narrator (and main villain) in the middle of action sequences, which really screws up the episode's pacing.
 * 9) The monster costumes look bad.
 * 10) Abrupt ending which doesn't resolve the plot in any real way. The producers were planning a sequel episode for Season 10, which presumably would have tied up the loose ends, but had to scrap it due to the bad reception of this episode.

Redeeming Qualities

 * 1) There's one occasion where the "found footage" style actually works well, when a commando thinks he's escaped the monsters by sealing himself in a room, only to find that he's sealed himself in there with another monster.
 * 2) Creepy ending shot with the main antagonist crumbling into powder as he addresses the audience.

Reception
The episode currently has the joint-lowest IMDb user score of any episode of the revived Doctor Who series (prior to the widely hated Season 11), along with the Season 2 episode "Fear Her". It also got the lowest viewing figures of any episode of the revival series up to that point.
