I'm 16 years old and watched all of these over the course of a week it all started when my teacher played httyd in class and I liked it so I decided to watch all of them in a week and I have to say it's truly an amazing series and we'll put together story it made me cry in the 2nd one and the 3rd made me ball like a girl and I'm usually not like that, but I'm speechless as was to say I love toothless I love the bonds I love the funny parts, I love the plot twist I became a huge fan over 5 days. The hidden world is a masterpiece conclusion to the storyline but I cried like a little girl seeing toothless say goodbye 🥺 anyways I love every bit of it and I will forever remember the movie
