Eh, I couldn't get into it. The Mudra thing seemed too overly anime. I know that's a weird complaint for a game like this, but it feels like it was really meant to appeal to the ADD Naruto crowd. And it also felt odd because in real life, Mudras refer specifically to a Hindu/Buddhist prayer gesture rather than a crazy ninja thing.

The Rogue quests, though, were top-tier awesome. And the sound design is particularly excellent. They're very satisfyingly slashy and metallic.
