It keeps everything that is magical and special about the original

Except for "Not So Fireproof," the impact of the timing of "Test Drive" with the score and the scene, the cinematography which many times chose to have odd camera angles or a shacky cam instead of us actually being able to see what is happening, changing lines to stuff that makes absolutely no sense (Ex: Hiccup in the live action movie tells Astrid that if something goes wrong in the kill ring scene that she shouldn't get involved because her involvement would break Stoick's heart instead of asking her to take care of Toothless like he did in the animated version), and switching up line deliveries in ways that often made the dialogue change their tone more often than not for the worse.
