>>333404503, 4, and 5 are all top tier. 1, if you watch the Birth of Mewtwo short as the opening (since it justifies the "tears of life" at the end), becomes passable if you ignore the very obvious dubbing flaws. 2 has its moments, but it at times feels like things are happening too fast and certain moments don't have enough time to breathe.
Heroes, to me, gets additional credit for actually going out on an outright downer ending. The music is also top tier, both in-movie and during the credits. And 3 gets credit also for having an "antagonist" who isn't in it just for teh evuls.
