Final Battle Scene:
This scene uses a lot of quick shots to portray action and chaos, as well as many upward shots of the huge dragon to portray its size and dominance of everything else. Although they break the 180 degree rule, it is because they are switching back and forth between characters that are doing different things, not interacting. Also, what makes me really enjoy this scene are the many following shots of Hiccup as he is riding Toothless, his dragon. Those aerial following shots really give the audience a feel of the immensity of the environment and what the vikings of the movie are up against. All in all it has very good cinematics that explain what is going on without the storytellers having to spell it out for you.
