Don't get why he keeps calling Kakashi the weakest Hokage in history (outside of Shikamaru) when the canon novels make it clear that his mastery of ninjutsu and chakra made him someone who could stand at close to or equal the Super Kage level (crushes 50 jonin with pure taijutsu, scares off three Kage level Iwa ninjas with purple lightning, blockades a village for an entire village with a special Quartz release technique that no one could breach, etc.), far more powerful than he would have been as a swordsman.
Outside of that, the story's okay.
