Didn't realise Kishimoto was an animator now.
You don't write action scenes to that degree in a screenplay, the choreography is down to the animation team who really made something unique and unlike-Naruto for the film's dramatic finale. Especially tiny details like Naruto and Sasuke's footspeed in a given 5 seconds, the animation team determines the angles, FpS and other specifics and thus control the action not the other way round.
