Note: I've watched all 4 seasons of Mu Wang Zhi Wang before writing this review, also this review will contain spoilers for previous seasons. First, this season changes models of all of the characters; most of the changes are subtle, though there are a few that might cause confusion. This time the season takes place after season 3, though some time may have passed in between. We are introduced to yet another new faction that seems to be after the lead position of the tomb guardians because of the current leaders' failure to keep the tombs guarded (though they seem to have personal ambitions for doingso as well).

As the newest (and likely final) season, the updated models make this show feel fresh and the animations are much smoother than previous seasons. However, the plot feels much worse. The fights are dynamic and exciting, but there are tons of perfect coincidences so that power-ups can happen. There is a lot of plotting, back stabbings, and team-ups that make no sense. Even the villain's final goal and endings feel way too forced.

Finally, while the ending leaves the possibility of a new season, it is highly unlikely. The plot at least wraps up most of the plot points from this season so there we viewers aren't left hanging. But it feels like a mess overall. An enjoyable watch, I would still recommend this.
