There’s no shortage of excitement, suspense, jokey camaraderie, sorrowful losses, satisfying comeuppances, twists and turns to fill the generous running time, with plenty of variation in the bloody encounters.

It’s a blockbuster that funnels the appeal of big-budget action and horror with an almost sacred reverence for the material. That’s absurd, but Snyder’s a true believer in go-for-broke escapism and at its best, the mayhem in Army of the Dead is an infectious zombie bite of its own.

In a way, this B-movie on an A budget gets closer to the values of George Romero, the godfather of zombie cinema, than Snyder’s actual, hyper-adrenalized remake of Romero’s masterpiece.

There’s enough gore, mayhem, and decay in Army of the Dead to make for a satisfying zombie-movie experience, and while it’s the best film Snyder has made since his last “of the Dead,” it’s also one that continually hints at the more satisfying work it might have been.

There’s a certain fun to be had in Army of the Dead, but it’s the mindless, ugly fun that you wake up the next day regretting. Come to think of it, it’s kind of like a trip to Las Vegas.
