Don't get me started on the 3 tail-arc.
The worst in order are, the Sora arc (FAKE KYUUBI WTF), then the Asuma bullshit, followed closely by the 3-tails.
Also the manga is obviously better since there's no filler bullshit. Also Danzo faps with his Uchiha arm to piss them off in their death lawl, Senju forever.
