Just got back from this,
As others have said, this movie is a honest-to-god comic book come to life. I love that they went with this style and cranked it up to a level possibly attainable by a touch of LSD. (Now fair warning, this film will assault your retinas like you wouldn't believe. But man, it just looks so friggin' good.)
The action scenes are really good, the soundtrack is a banger, and there's plenty of heart and humor I'd expect a Spiderman movie to have.
Overall, it's a great Spiderman movie, a great superhero film in general which is saying something in a already stacked year, and as for a animated film, for me it's bar none the best one this year.
