Have I already posted something like this? Yes. Am I gonna do this anyway? Also yes.
Reasons why you should read the How To Train Your Dragon books if you haven't already (regardless of whether or not you're a fan of the movies)
The drawings throughout the books can range from being silly little doodles one moment to unforgettable portrayals of some of the most intense scenes in fiction you'll ever read.
Toothless is A Baby (and a bit of an asshole, but in the same way that a cat is an asshole).
Hiccup can verbally communicate with dragons, and the dragon language is canonically composed out of absolute nonsense
Fishlegs is ten times more important to the story due to being Hiccup's best friend, and he also has an incredibly lovely arc of his own.
Speaking of arcs, Hiccup's arc throughout the series is a beautiful portrayal of a misfit becoming a hero in his own way and advocating for the rejection of all of the flawed ideals that his ancestors put into place.
Seriously, this is a book series about choosing to be intelligent, imaginative, and empathetic in a society that wants you to be the opposite of all of that.
While Astrid is great, Camicazi---the character who was probably her jumping-off point, since they both have a dragon named Stormfly---is a feral gremlin of a girl who we should all aspire to be (also, as far as I can recall, there's never any hints of there being something romantic between her and Hiccup, or her and Fishlegs---it's just a great platonic friendship between the three of them, which is a win for me personally).
Alvin the fucking Treacherous. This, to me, is something that the movies absolutely should've added, because he is one of the best goddamn villains... ever. I genuinely cannot think of any other piece of media that shows the main antagonist developing side-by-side alongside the hero, becoming a worse and worse threat as the story gets darker and the stakes get higher, but my god did it rewire my mind as a kid... and for spoilers, that's all I'll say about it!
The dragon designs are the. Most. Fun. Every single kind of dragon in this series is unique, memorable, and more often than not, really hammers in the fact that "dragon" is a word that encompasses a vast number of traits---really, it just means a creature that's weird and somewhat reptillian, and these books take that concept and run. With. It.
THE LORE AND FORESHADOWING IS FUCKING LEGENDARY. If I go into any detail, I will spoil so much, but let it be known that if you're writing a story, and you want to work in foreshadowing and big reveals in both a mystery and a blink-and-you'll-miss-it fashion, these books are a masterclass in how to do it. Loose threads that you don't even know existed will be woven in right when you least expect it.
Honestly... I don't think it's too much of a stretch to compare How To Train Your Dragon to Adventure Time, because their way of storytelling is similar in all the best ways. Yes, at first, it leans more on the comedic side of things, but as you delve further into the story, it unfolds into a truly fascinating epic about growing up and what it means to be a hero... and it also gets very, very dark. I'm not exaggerating when I say that some parts of the later books gave me nightmares, and I loved every second of it.
