The episode was quite good (except for the many flashbacks, they just can't stop dragging everything out since shippuuden began
But the rest was fine, the battle looked good and I kinda liked the Music.
They still should stop dragging the story so much, especially after the long filler period.
Nothing against flashbacks, but Kabuto and Orochimaru talked about the story as if they were trying to tell the audience what has happened in case not everybody has seen/ does remember the scenes from Naruto. The others were not so bad I impov.
