Watership Down/YMMV

All adaptations

 * Alternative Character Interpretation: Frith, the Sun God and creator of the world.
 * Even within the stories themselves, Prince Rainbow's role varies -- sometimes he'll be against El-ahrairah, other times he'll help him with good advice.
 * Fandom Rivalry: Watership Down vs. The Animals of Farthing Wood
 * He's Just Hiding:.
 * Nightmare Fuel: The Black Rabbit of Inlé.
 * Just about every one of Fiver's visions, Bigwig's encounter with the Shining Wire, and the poisoning of the Sandleford Warren, to name a few. The film tends toward either short and surreal (the visions and flashbacks) or realistic and gritty (all the violence portrayed in the present tense), while the book has longer descriptions. Pick your poison, and know this stuff can be disturbing to more than just kids.
 * Stoic Woobie: Blackavar pretty much defines the trope.
 * Tear Jerker: Painful tears in the film during the "Bright Eyes" sequence. Joyful tears at the end of the book, especially at Vilthuril's storytelling.
 * The Woobie: Blackavar in the book and film.
 * Fiver again, especially in the film and TV series. Then again, it's hard to imagine how an adorable little rabbit who is totally lost without his big brother and who suffers from violent hallucinations wouldn't be a Woobie. He used to get kicked around a lot apparently and the rabbits who follow him need quite some time until they believe he DOES see things.  Just the type of wild rabbit you would pick up, cuddle and take home if you'd find him half tharn in a meadow.
 * In the novel, Pipkin, as well. Even smaller and weaker than Fiver.
 * In the TV series, Campion also fits the bill. Sometimes.

Novel
"The beetles died in the frost and my heart is dark;
 * Magnificent Bastard: General Woundwort.
 * Nightmare Fuel: The White Blindess (Myxomatosis.) Keep in mind that it was deliberately introduced by humans to control the rabbit population.
 * Paranoia Fuel: The book does an excellent job of making you know what it feels like to be an object of prey.
 * Tear Jerker: "The wires..."
 * "Fiver Beyond" (basis for the Bright Eyes sequence)
 * "For El-Ahrairah to cry" (destruction of the warren)
 * "El-Ahrairah and the Black Rabbit of Inle"
 * The end
 * Let's face it, the whole thing.
 * The poem of Hyzenthlay the Efrafan doe, quoted here

And I shall never choose a mate again.

The frost is falling, the frost falls into my body,

My nostrils, my ears are torpid under the frost.

The swift will come in the spring, crying “News! News!

Does, flow with milk and dig holes for your litters!”

I shall not hear. The embryos return

Into my dulled body. Across my sleep

There runs a wire fence to imprison the wind.

I shall never feel the wind blowing again."


 * Woolseyism: The translations from Lapine are sometimes presented this way. For example: Bigwig's name in Lapine is Thlayli. The literal meaning is "Fur-head", but "Bigwig" is an even more apt way of putting it, since he's also a senior officer of the warren.

Film

 * Animation Age Ghetto: The reason why so many kids were traumatized by the animated movie.
 * Nightmare Fuel: Especially the flashback of when the Doomed Hometown Sandelford
 * Tear Jerker: And how.
 * What Do You Mean It's Not for Kids?: At least, not for young kids.
 * Although any parent who'd seen the original trailer first had no excuse whatsoever for invoking this trope.

TV Series

 * Awesome Music: Mike Batt, who wrote "Bright Eyes" in the film, returned to make some awesome tracks.
 * Harsher in Hindsight: The Covered Up of "Bright Eyes" that was recorded for this series was performed by Stephen Gately of the Irish Boy Band Boyzone. Most fan complaints over this were promptly silenced following Gately's death in 2009, and if anything, makes the song even more of a Tear Jerker.
 * The Scrappy: A lot of fans hate Primrose for being manipulative, self-centered, and good at nothing else.
 * Strangled by the Red String: Campion and Blackberry. In the season 2 finale, they meet very briefly and barely have time to speak to each other before and their consequential separation. Of course, they pine for each other, and all the other characters, who are strangely aware the two's feelings for each other, try to comfort them for their loses.

Lapine mythology
"Embleer Frith."
 * Family-Unfriendly Aesop: Since these are prey animals, a bit of Values Dissonance may be present.
 * Which is sometimes Lampshaded by the narration, as when it's pointed out that rabbits feel no guilt or shame about using physical force to push weaker rabbits around.
 * Nightmare Fuel:
 * Several. The Black Rabbit of Inlé, The Hole in the Sky, the Terrible Hay-Making...
 * The Hole in the Sky involves El-ahrairah hearing of the titular phenomenon and going in search of it. After losing a fight with a weasel and falling into an infection-driven fever, he unexpectedly finds it:


 * And then you realize that Richard Adams was a soldier, and start wondering where he got the idea...
 * What makes it even more disturbing is that Adams offers no explanation of what the Hole in the Sky is or what it means. It is, quite simply, a rabbit thing that humans would never understand.
