If that didn't hit me in the feels, I don't know what else could! This is such an excellent tribute to the books. I remember ages back when Dean first said he wanted the story to end with this quote, and I thought that that would be AMAZING, but I assumed he just meant he wanted to have that general vibe. I did NOT expect to hear Hiccup voicing those words. The HTTYD story is coming full circle, respecting it's book roots, while at the same time making bold steps in its own direction. The whole first part of the trailer (along with the song) is totally geared towards hitting the nostalgia of the older fans. It grabs those of us who remember first watching Forbidden Friendship, who cheered at the release of the second movies first teaser, and who read the books even though they were so different from the films. It hit me HARD, and I was already almost completely convinced that I was gonna love the trailer even before the really showed us any footage.
Ok, bearded Hiccup? Yeah, I'm cool with it. To be fair, I don't have many protagonists that I adore who are bearded, and I'm not necessarily planning on growing one (although that might change now!). However, as a Viking cheif, it feels really fitting. It also makes him really feel like he has matured. Sure, he's the same person, but his role now seems to be that of a wise leader, not a brave and reckless explorer. I am glad that he won't have this much facial hair throughout the majority of the film, but I will say I am really pleased with it. It is also a really, really nice homage to Stoick. Hiccup even has the diamond-shaped armor and the fur cape (plus little Night Fury clasps... and does Toothless's chest look broader? My, he is a handsome dragon!). He has filled the huge boots his father left for him... in his own way, but nevertheless in a way that would make his father proud.
