Does anybody feel that the series should change its name to Uchiha Shippuden instead of 火影忍者 Shippuden?

Of course not!!! Why would I think that? The series is about Naruto, not the Uchiha clan, though Uchihas do feature in it prominently, however, 火影忍者 is still the main character and he's 更多 awesome than any Uchiha! He deserves to have the series named after him!
