Loved every minute. It was fast, funny, nostalgic, and new at the same time. The characters are the same, but all the relationships get flipped. It is so tongue-in-cheek that the superhero aspect does not even try to compete with all the others out there. And this is a live action/CGI cartoon, not a comic book, and the plot at all times is clear and easy to follow.
The credits are almost as long as the film, but worth sitting through them, as we are supposed to do, because there are three or four additional scenes scattered through, and the final one, closing the credits, also closes the film! Enjoy.
