Httyd is so wrong to me in many ways, like how much they changed Toothless behavior, or additing a girl dragon only to make his separation with Hiccup make more sense, or the villain being "The One" slayed all the night furies, or the fact they didn’t needed for the dragons to be gone, like, at all.
The dragons from the start were a metaphor for prejudice, how knowing the other allows you to live better with them and THAT takes time, takes patience, takes adaptation, this is shown not only in the first movie, but in the series too, so its very weird for them to throw it all away because "the world isn't ready for them"?
Hiccup already fought with SO MANY antagonists who had the ideas of hunting/ dominating dragons, he fought so many for the coexistence, only for the dragons to have to hide in the end? Like the world wasn't meant for both humans and dragons at all?
Hiccup would make the whole world understand if he needed, he would make the world for the dragons.
And I ain't talking abt "Oh no I wanted Toothless and Hiccup to still be together in the end", im talking abt how this doesn't make sense and feels like throwing things away for the sake of the easiest ending.
