Caleb Villa’s review published on Letterboxd:
Snyder's allergy to nuance should be cured by a four-hour runtime; instead, it is exacerbated. It's not that I didn't enjoy my time spent with these legendary characters, and in the moment, I was swept away by Snyder's penchant for brilliant iconography (the 4:3 aspect ratio is a perceptive choice on his part, lending these heroes more mythical gravitas than they've ever had). Yet it doesn't feel long, which is actually to its detriment. If you have 242 minutes to use, spend it on an intricate plot! Or character arcs for more than two heroes! Or a unifying theme explored in multiple ways! The Lord of the Rings films or The Irishman or the BBC Jane Austen adaptations have meat to them and feel long, and I couldn't be happier that they do. Zack Snyder's Justice League feels short because it's a breezy compilation of cool characters doing some fun things. But is the core story here any more interesting than the one delivered in the offensively dull 2017 version? Not a smidge. After all, the groundwork for both cuts is identical.
