Tite Kubo's Bleach does many things right as part of the big three, from its fun reverse-isekai elements to the power of friendship with swords to shake up the shonen combat formula. However, while Bleach has some solid drama and dialogue as well, too much of that drama comes from a shallow source: overuse of the tsundere character archetype. Bleach simply has too many tsunderes for its own good.
