I believe many of us agree that Kaguya's appearance in the War Arc was unexpected and didn't receive the attention it deserved. Instead, Madara should have been the final villain with Sasuke as the final battle. Kaguya's threat could have been introduced a few years later, perhaps around The Last, and given ample time to develop through OVAs or a movie. This would bridge the gap to Boruto and create a significant event during the blank period. What are your thoughts on this?
