the best stuff is still yet to come.

This episode expanded on the manga quite a bit, I wouldn't call it filler, it just let us in the know more.

Like we didn't really see those ninjas throwing shurkiens or blowing fire on those snakes invading the west gate. We saw them break though, but then it cut back to the stadium a few panels later.

Also, I like how they make the ANBU look all cool in this episode.
