An improvement but not a massive vindication, it's like jumping from an 4/10 to a scratching 6/10. Barely good enough, more indulgent than BvS and the core issues that the 2017 movie had are still there but less agressive this time.
The fact is, there's going to be a contingent of viewers who are never going to like Snyder's style of superhero films because they're a reflection of him and his visual storytelling style. That's fair, not everyone's a fan.
But he still made a good and interesting film on it's own merits. Just because they aren't the derivative Disney variant of superhero flick churned out by Disney/Marvel doesn't mean there's no space or appreciation for such. I have grown tired of their style and it's basically completely subsumed the style of superhero film and pushed out any other variation.
I am glad to have the DC films being themselves and not chasing after Marvel's coattails. Let it be dark. Let it be stylistic and reflect itself. I don't need WB corporate trying to emulate what made Marvel successful.
