The adventures of a Time Lord—a time-travelling humanoid alien known as the Doctor—who explores the universe in his TARDIS, a sentient time-travelling space ship. Its exterior appears as a blue British police box, which was a common sight in Britain in 1963 when the series first aired. Along with a succession of companions, the Doctor faces a variety of foes while working to save civilisations, help ordinary people, and right wrongs.
This tv show contains 78 potentially triggering events.
The climax to “The Happiness Patrol” shows the main villain crying over her dog, Fifi, who is dying by the hands of the main cast.
K9, who is a robot dog, is also destroyed multiple times - but always gets restored.
References to ancient Egyptian deities and the portrayal of Sutekh as a powerful being with god-like abilities can be likened to demons or concepts associated with Hell.
Part 2:
There's a dead rabbit carried by the hunter around 5 minutes into Part 2. The rabbit looked realistic, and it was kind of far away but moved like I would imagine a dead rabbit would, suggesting it might not have been fake. It would have been an exceptional prop for the 1970s if fake.
"Survival", part 2: Lots of animal bones, and in a couple of scenes large animal corpses partly eaten by scavengers. (The corpses are fairly visibly artificial props and not real corpses, if that makes a difference.)
There's a dead rabbit carried by the hunter. The hunter has a dead rabbit with him as he runs away, not sure if it was elsewhere in the episode and I missed it. No idea if any animals were harmed in the making-- it looked pretty real but wasn't close up.
"Desperate Measures": A character shoots what she thinks is a wild animal, but turns out to be another character's pet. The other character is visibly distraught.
"Sentence of Death": A male character threatens to backhand a woman, but is prevented. Later the same male character is heard but not seen slapping a different woman.
"The Meddling Monk": It's implied that a woman was raped, but the event itself is not shown; her attacker grabs her, and then it cuts to her in a state of shock some time later.
"The Meddling Monk": It's implied that a woman was raped, but the event itself is not shown; her attacker grabs her, and then it cuts to her in a state of shock some time later.
"Guests of Madame Guillotine": Execution by decapitation. The blade is seen as it begins its descent, but the victim is not shown during or after the moment of decapitation.
Multiple people are strangled/choked in Pyramids of Mars.
Part 1:
Collins is killed offscreen after the Doctor and Sarah leave the storage room. The mummy case moves after they leave, and Collins is found dead shortly afterward in the study. (Timestamp not specified)
Namin is killed by the alien at the end of Part 1/beginning of Part 2. (Skip from Namin's plea to be spared)
Part 2:
Warlock is strangled by a mummy around 9:38 into Part 2.
At the end of Part 2, around 24 minutes, a mummy approaches Sarah Jane and places a hand on her neck. (No harm done; resolved in Part 3)
"Johnny Ringo": A character is threatened with hanging and it gets as far as a noose being placed around his neck, but he is rescued before the noose is tightened or elevated.
Part 2: Around 4 minutes into Part 2 of Pyramids of Mars, the Doctor takes a full force of a blast (no explosion) and falls unconscious. Sarah Jane tries to wake him around 5:45. He actually wakes up around 11 minutes into Part 2.
"A Holiday for the Doctor": A character has to have a tooth removed without anesthetic. The actual removal is not shown on screen, just the lead-up and aftermath.
"The Planet of Decision": There is an extended sequence involving a precarious climb down from a great height, including a character who is terrified and nearly faints, and several points where people *nearly* fall - but in the end, everyone involved survives unharmed.
The Doctor and the Master both regenerate multiple times, which occurs after a Time Lord is mortally wounded. One of the Doctor's companions dies in a massive spaceship crash.
"The Curse of Fenric", part 3: A character who uses a wheelchair is portrayed by an able-bodied actor. At the end of the episode, he regains the use of his legs through supernatural means.
"The Macra Terror" part 1: The association between mental illness and violence is made by characters within the story, with a character claimed to be mentally ill and violent. (He's actually not mentally ill and only threatens violence in self-defence from being persecuted.)
In "Pyramids of Mars," reality is portrayed as unstable due to Sutekh's ability to manipulate it. Sarah Jane sees Sutekh's face projected into the TARDIS, illustrating his influence on distorting perceptions and creating an atmosphere of instability throughout the episode.
There are multiple scenes that might be considered claustrophobic, like when they hide in a chest/trunk (beginning of part 2) or when they hide in a priest hole while the Doctor is unconscious.
Inside Sutekh's tomb and mummy case has some light effects at times. Examples are 15 minutes into part 4, where three columns (take up maybe half of the screen overall) have some lights moving around. The part that seemed the most offensive to my vestibular system was about 6:15 into part 4, with many lights moving within a mummy case shape, as if the item within it were traveling down a large time-space tunnel toward the opening of the case. The lights move more quickly and there are multiple colors that contrast starkly with the black void behind them. Otherwise, it's pretty tame.
The N-word is used once in the series during the second part (The Hall of Dolls) of the 1966 story The Celestial Toymaker. A character played by a white actor uses the word while reciting an early version of the "eeny, meeny, miny, moe" nursery rhyme.
Like many stories from the first six seasons this story no longer exists in full so (at the time of writing) you will not see it when watching the show on streaming services or DVDs. The official release of the audio from the story includes narration over the N-word so it is inaudible. Fan-made reconstructions of the missing episode usually deliberately distort and muffle the audio so it is similarly inaudible.
"Survival", part 3: No characters in this story are explicitly identified as LGBT, but there is romantic subtext between two female characters (which the writer has confirmed was intentional), and one of those characters dies.
The Doctor is hundreds of years old while their companions are all quite young. While there are no explicit romances between the Doctor and any of their companions, their relationships specifically with Sarah Jane Smith and Jaime McCrimmon can be read as romantic. In both of those cases, yes - there is a large age gap.
This very much depends on who you ask. Most stories have fairly tame endings, but since the show was cancelled before certain arcs could be resolved, the ending of the series as a whole could be considered sad.
The Fourth Doctor episode "The Deadly Assassin" has more on-screen blood than any other Doctor Who episodes I've seen. Blood is shown dripping down the Doctor's leg when he's injured. Blood is also shown very clearly on his arm and shirt when he's shot.
K9, who is a robot dog, is also destroyed multiple times - but always gets restored.
