This movie is an exhilarating and memorable ride. Despite a few bad puns, the writing is exceptional. I was a huge fan of the repetition of certain phrases that, when placed in different contexts, showed new meaning. I liked the play on words with the concept of "dragon training," and how it did a complete reversal from what it was in the beginning of the movie. To me, the writers clearly treated this film with care, intellect, and a faith and respect in their audience that is a rarity in "kids" movies these days. That kind of attention to detail was present in their incredible graphics as well, even though I didn't see it in 3D (I think they give me more headaches than they're worth). Without going for the cuteness of Pixar or the realism of Beowulf, they managed a charismatic and charming style that feels appropriate for the subject matter and wholly original.
There were a few things I didn't like about the movie, however. First, Baruchel's voicing of Hiccup was irritating. By about 10 minutes in, I just got annoyed at his whiny, monotonous tenor and wished he was played by anybody else, even Michael Cera. Second, the fight and reunion with his father felt written and didn't quite ring true, although it nonetheless contained some tearjerking ability. Third, there were some aspects of the plot I didn't (and still don't) get, but they're relatively minor and don't really hinder your enjoyment of the film. This movie goes wholly recommended by me, because it has just about everything you could ask for in a film, including the all-important entertainment value.
