Kevin Seiler’s review published on Letterboxd:
I mean for what it's worth, it exceeded my expectations. Those expectations were incredibly low, but it is what it is. It suffers from some of the same problems that BVS did, but to lesser degree as the four hour runtime allows scenes to actually play out rather than dart frantically from one to the next. There's still very little here in terms of character moments or actual dialogue, as there's simply too much plot to get through, and I still feel like they could have taken their time with the DCEU as a whole and we would have gotten a more cohesive movie in the end as a result.
The muted color palette of the entire thing makes sunshine look dreary, and the entire climactic fight at Steppenwolf's stronghold looks like something out of a shitty first person shooter video game from 15 years ago. Everything is black and brown and explosion colored, and it's visually boring. The tone of the entire thing is still overly serious, as Snyder has already done in Man of Steel and BVS, but at least the tone stays consistent throughout the Snyder League: A Zach Snyder Story, as opposed to having bits of Whedon quips and silliness peppered throughout. I remember very little from the theatrical cut, but I do remember how out of place those moments felt.
I don't hate it, but I can't really bring myself to say it's good. It's fine. It's leagues ahead (no pun intended) of BVS and the absolute cinematic flatline that was theatrical cut. It doesn't redeem the entire DCEU, but it's definitely an improvement over the Justice League movie they gave us before. I'm still not a fan of Snyder's movies, but I don't regret watching this.
Now give us the Ayer cut of Suicide Squad.
