Having actually seen the entire movie, I feel the need to mention that anyone dissing individual scenes of KnK5 is doing the movie an injustice because while individual scenes might seem out of place or weird when viewed on their own, the entire movie itself a visual tour de force which builds upon every scene and every moment, both visually and musically, and flows in such a brilliantly engineered way that it all works.
It is an animation film where the direction trumps over all other aspects of the movie, and everything element of the film is simply an aspect of the overall direction which does not really stand alone. Every scene, every piece of music, every line is simply a part of a narrative puzzle box which unravels part by part as the film unfolds in a dynamic and elegant way which few movies are capable of doing.
