The chemistry between Sanzo, Hakkai, Gojyo, and Goku is so lived-in that filler episodes become the point, watching them bicker and protect each other matters more than the plot. The comedy lands because the show trusts you to care about these four people before it asks you to save the world. A road trip where the destination is secondary to who you're traveling with.
Priest Genjo Sanzo and his three companions, Cho Hakkai, Sha Gojyo and Son Goku, press on with their journey west. Their goal is to stop the demon Gyoumao from being brought back to life. The group, known as the Sanzo Ikkou, now has a reputation that travels ahead of them, and demon assassins attack them at every turn. Tensions are also rising among the four, and they must deal with that strain if they are to defeat a powerful enemy. The series is a fantasy adventure that mixes action and comedy with drama.
