Jaime Rebanal’s review published on Letterboxd:
This is probably the first time I've felt like a Zack Snyder movie seems to be so much longer than it actually is; and it's also quite detrimental towards the final product. But given as Zack Snyder isn't working with all that much beyond the surface of Army of the Dead, he still turns the film into one that's reflective of the hierarchies established by the United States government, its failures, all brilliantly within its Las Vegas-set world-building.
The cast is also clearly having a fun time with their roles here; Dave Bautista's part in particular is one that echoes much of Snyder himself and is often heartbreaking for that reason too. Also wonderful is Tig Notaro, who plays her own parts flawlessly as if she were there from the start.
But I'm down with Zack Snyder being honest about how much fun he wants to have, because he definitely knows how to bring it to his audiences too.
