You know the story. Boy finds freak; boy befriends freak; men in power see freak as threat and try to capture/kill freak friend; you sit through the credits hoping the darkness will hide your tears. And this time our freak is: the dragon. Because aliens and giant robots filling the role still were never quite nerdy enough.
I hope it ends with him freeing the dragon for its own good, in the same way Willy had to be freed. By which I mean to the music of Michael Jackson.
