a splendid movie!
it had sonic, squidward as the shakespeare's othello, who advices sonic to take care in his trip to hell, because it would change him forever, and since this would happen, he would have to restore his fractured friendship with knuckles before he would leave...
after that, we see a touching discussion between sonic and eggman as they discuss the morals of good VS evil, and the various points of view that a war can bring into ones mind.
then, the descent of sonic into hell in order to save patrick the star, and tails the fox was truly the best piece of the movie, since it showed the evil antagonist: lord blachk himself.
truly a great part of a great movie, and i would love to see the sequel in this, because it would be great!
