Shadow (2018)

Same director - same aesthetic but in color. Both are wuxia, both share intrigues and heart-break about the hazard of events that is life.
The stories are both epic.

Both have the concept of "shadows", a historical setting, and a unique, striking color palette and style.

Same director so the style comes off pretty similar. Both are slow to start and visually stunning movies- one is very colorful while the other is grey monotone.

Set in the Sengoku Period. Retired from ninja duty, Torakage lives a peaceful life in a small village with his wife and son. One day, Torakage’s son is kidnapped by his former master in an attempt to force him to break into a nearby castle and steal the Gold Scroll, the counterpart to her Silver Scroll, the two of which when brought together point the way to a vast treasure. Having no choice, Torakage and his wife sneak into the castle. However, their plan goes awry and the two are caught and turned over to the evil lord. Now, with his wife a hostage of the lord, Torakage must bring him the Silver Scroll held by his former master or forfeit her life! Utilizing weaponry crafted by an eccentric inventor, Torakage takes on both sides and plays them and their ninja armies off each other in the hope of saving his family.
