Army of the Dead proves that Zack Snyder only really has one idea of his own when it comes to keeping "zombie stuff" from getting stale after more than five decades.
Luckily, it also proves that he can build out from it fairly well.
Animation - especially feature film animation - has never been in a better place than it is right now. To the point where the Disney/Pixar machine can be enjoying their best creative streak in decades (if not ever) and yet even their fine-tuned story machines like Zootopia, Soul and Raya and the Last Dragon wind up feeling somewhat upstaged by films like Your Name, Wolfwalkers, and - now - The Mitchells vs. The Machines.
