Part of the plot involves a science-fictional menace affecting the fabric of reality, resulting in events like a person being able to walk through a closed door.
This listing is for the 1996 TV movie, not the TV show. It's assumed drugs are used on the Doctor after he is shot, but no one does actual drugs on screen.
It isn't graphic, but the scene towards the end of the film when the villain catches the protagonist and chains them up could definitely be perceived as torture.
There's a pretty uncomfortable and distressing hospital scene where the main character is on an operating table after nearly dying in the crossfire of a fight- and they struggle to warn the surgeon that they aren't human, to no avail. Tread with caution.
Users mistake this entry for the show. The main character who is often interpreted as either aromantic/asexual or bisexual "dies" briefly, but comes back.
It depends on who you ask. Once again, this listing is for the 1996 Doctor Who TV movie, not the show itself. It ends with the Doctor going off with no companions by his side. This could be considered sad, but it isn't necessarily framed that way.
Users mistake this entry for the show. There are no nuclear explosions in this movie. However, there still is an apocalyptic scale threat. Tread lightly.
