Oh boy, surely a cheerful and not at all terrifying tale!

I was about to snark that parents that give a fuck can refer to a movie's age rating but then I learnt that, until recently, it was classified in the UK as U (universal, suitable for all) because "Animation removes the realistic gory horror in the occasional scenes of violence and bloodshed". That's certainly a view. Good thing to know that I just have to animate all of the fucked-up shit in my head and that makes it okay to sell to children. (https://en.m.wikipedia.org/wiki/Watership_Down_(film))
Edit: 6 and up in Germany. Cool. Cool cool cool.
- I remember watching this in school... as a treat
  
  What did you do to that poor substitute teacher???
  
  I think you misspelled "threat"..
- So Heavy Metal rates U?
  
  Only if you blur all the boobs. Remember, grotesque violence is okay but the human body is an abomination never to be seen
- Using Boost for Lemmy? Also having issues with the Wikipedia link? Here's a working hyperlink: https://en.m.wikipedia.org/wiki/Watership_Down_(film)
- The Animals of Farthing Wood was the hot shit when I was in elementary school.
  To be fair it is not that gory, it is mostly just genocide
- Lol, stuff like Hellsing Ultimate must've given them a reality check.

I don't know how but somehow I managed to avoid this one as a kid. I rented tons of videos and this one was square in the middle of them, but something about it made me avoid it like the plague. And this was long before internet, nor did any of my peers see it and tell me about it. Knowing how frail my mind was at that age, that was undoubtedly a good thing.
- Same here, I have no clue how I avoided this one either. Maybe my parents guided me away every time I reached for it and I just don't remember? I honestly don't know.
  
  My parents had it for us at home. What does that say?
- Maybe the place where you rented movies had a version with this cover
  
  Lol it did, this brings back memories. I also seem to remember a still image of a roadkilled bunny(?) on the back which threw me off. But maybe that's just Mandela effect.
- Watch it now, tell us if you are any less frail
  
  Considering my current tastes in media, i doubt it'd do much. Although I've always had a soft spot for animals, even the animated kind.

It was some terrifying stuff. The vision Fiver has. Holy crap. Even the intro with Frith and the animals...it was dark but epic. Young me was scared shitless, but older me kind of liked it (And was also scared shitless).

- That's the good stuff, right there.

Pairs well with a brave little appliance
- Still my favorite animated film but I am a simple man.
- I still wonder how the power cord bled when the bad man chopped it, or is that a false memory?

‘The Big Friendly Giant’ yeah fuck this shit. More like Giants eating kids while they sleep because they can smell their flesh.
Watership down
Grave of the fireflies
The big fucking giant
Trifecta of nightmares
- Roald Dahl's stories were nightmare fuel if they were written by anyone else, because his style just made it seem so goofy. Just think of fantastic mr. fox: the entire countryside is destroyed as a titan of the industrial age brutally hunts down pitiful animals trying to scrape by. The witches? Literal torture porn as children are changed into mice and put through all manners of hell.
  Even his semi-autobiography was about how children tortured each other in boarding schools. I remember his tales of having to warm up a toilet for the older boy in charge of him, and how they were all whipped/caned by the older students.
- The secret of NIMH?
- How you gonna do Fleshlumpeater like that?

This movie about fireflies also looks cute, and it's made by Studio Ghibli!

Kids going to watch the bunny movie and instead learning what happens when you accidentally put male and female hamsters in the same cage.
- They hug 🤗
  
  really fast
  
  After they hug too many times, the girl hamster starts to get a bigger belly and then tells the boy hamster to go away. Since the boy hamster can't go anywhere, the girl hamster eats his face while you're at school. The end.

For a slice of US Gen X we can remember our parents having us all gather to watch this when it aired on TV. I was at a dinner party with like 20 kids total all under 13 years old. When the scene we all remember from this movie happened it was pure chaos for like 30 minutes. I remember my best friend’s dad, who was my priest, saying “Gee whiz! Why in the name of all that is holy would they put a bunny cartoon on prime time and kill the bunny without warning everyone!” Never heard a man say “Gee Whiz” with that much vitriol.

My mum did this. I made it to the first death (hawk) and ran crying into the kitchen where she was. I was 4.
Then my first husband did this! He got me the DVD and it is still unwatched in the plastic wrap.
My current husband downloaded plague dogs because it's criterion and that rests unwatched on the hard drive because I cannot even watch anything by this director.
However, I did read the book Watership Down in college, and wasn't traumatized. I also collect copies of the book Private Life of the Rabbit which Richard Adams used as a source book

Reminds me of something from the opposite end of the lifespan. When I was young, they didn't clear the theater after a movie, and they sometimes had "double features" where they'd alternate between two movies and you could watch both for one ticket price. My dad's aunt lived with us (she was probably in her 70s at this point), and one day a couple of her friends picked her up to go watch "a double features of animal movies" at the local theater. They dropped her off some hours later and her face was grey - she said it was horrible, and didn't want to talk about it.
It turned out the double features was Day of the Animals and Night of the Grizzly, basically both horror movies. They didn't think they were allowed to leave during the movie, so they stayed through both.

Still to this day this is one of my favorite books. I was given it as a kid because I had a pet rabbit. Bigwig is badass.
- "Silflay hraka, u embleer rah!"
  I still remember that even though it's been over a decade since I last read the book. XD

I'm fuckin traumatized from this damn movie
- Suffocating rabbits and rabbit murder gave me nightmares as a kid. I literally haven’t watched it in probably 40+ years.

How has no one in the comments mentioned The Secret of NIMH yet?
Even worse, The Brave Frog (showa-era kids anime was seriously fucked up).
- The secret of NIMH was brutal as a small child.

But what IS a watership?
- Like an airship but for, you know, water.
  
  Buoyancy Operated Aquatic Transport?
  
  Like it's made of water? Like a submarine??
- It's old English meaning kind of "uplands near a watery place". Its an actual place near where I live, about 5 miles south of Newbury, Berkshire, England.
  Andrew Lloyd Webber lives just to the North of it and De Haviland did his maiden flight to the West of it just on the other side of the A34 road.
  The author lived there as a child, interestingly so did the author of Paddington Bear
  
  Yo Paddington is wicked sick. He's a rare sort of bear

If you watch the trailer it's kinda clear it was not meant for kids. Watched it in 4th grade, loved it.

I was a happy sun child before watching that... Afterwards I was emo and hated the world for existing.

Now available as a double pack with The Plague Dogs!

Just like this lovely story about a husband and wife living their best life.
When the Wind Blows trailer

Seagull says piss off was a real edgy moment for 6 year old me

In a similar vein, the opening credits to Animals of Farthing Wood will stick with me forever.

Double featured with Pom Poko and you really hammer it home

Harden the fuck up, kids! It's time to grow up.

I didn't think the movie was all that bad, but I had a pretty good imagination so I remembered all the horrors from the book. The scene that did feel strange to me is when hazel is tripping balls. Something with that song had it plastered all over my memory.
