These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Brothers Lionheart
Crowning Moment of Heartwarming: Just how the book and movie is used in Sweden. At several hospitals the book is read, or the movie is shown, to children who are dying or gravely ill. The effect it has on these children, and the extent to which the story has been shown to relieve children's fear of death and of dying, is truly beyond words.
Crowning Music of Awesome: The entire score by Björn Isfält. The usage of an organ as the main instrument elevates the score even further, given how organs are often played at funerals and the bulk of the movie takes place in the afterlife.
Thorn Rose Valley's liberation song. You don't even need to speak the language, the instrumental part playing at the end as the brothers ride home gives this troper chills every time.
Memetic Mutation: "All makt åt Tengil, vår befriare! / All power to Tengil, our liberator"
With the obvious counter "Död åt Tengil!/Death to Tengil!"
Narm Charm: The movie. It's very much a product of the seventies and has its corny moments but that's really part of the charm. And even with all that it's still an incredibly gripping movie.
Nightmare Fuel: Katla in the movies may seem silly both by modern standards, yet countless children have had nightmares because of her.
Purity Sue: Jonatan Lionheart. He was already described as a fairy tale prince before Nangijala. He could do anything, understand everything, he was stronger than anyone else, and everyone else wanted to be with him. That was before he started to lead a rebellion. And it works. It works beautifully, because the story is told by the hero-worshipping Skorpan — and in the end (though Skorpan himself says differently in the story introduction) the story isn't about Jonathan, but about Skorpan and his very touching relationship with his practically perfect older brother.
Special Effects Failure: The matte paintings are not exactly discreet. Also Katla, who looks like she was made from paper-mache.
