matt lynch’s review published on Letterboxd:
A whole hell of a lot. Snyder fully commits to big, sappy emotions and weird grandiose gestures, and the result is that this is bizarrely most interesting in its first half with all the shoe leather of bringing these now much more fleshed out characters together. Unfortunately a lot of the reconstituted footage is riddled with shoddy VFX and the action beats remain mostly unchanged crummy digital smears, only now they go on much, much longer. Still it's a ridiculous miracle of sorts that this even exists at all, so unwieldy and sincere that it frankly transcends good and bad and becomes purely artifactual, and I never thought I'd say this but I'm mildly bummed he's not going to get to do more of these.
