There's a point in Justice League when I started to say, "Hey, this ain't my little brother's Superman."
Full disclosure, I don't have a little brother and never had that point. I just wanted to say that and now I feel a little ashamed.
Batman has a parademon problem and thinks he's gonna need some buds to help him out. He gathers Wonder Woman, Aquaman, Flash, and zombie Superman up and they get to punching shit. That's about it.
If you come to these superhero movies looking for anything other than two to three hours of explosions then brother or sister, you need to shut the computer and take a walk. Even Christopher Nolan could not move this genre out of the "punch it until it's ideologically sound." If you say different, well, I'm happy for you.
I say that to say this: DC has produced the bottom of the barrel of content. Wonder Woman is the exception that proves the rule. Given her screen time here, I hope you saw the acting talent Snyder gave her ass.
So when I say that this movie is passable as a hungover Sunday indulgence, I do not say that lightly. A few jokes land, you can see the action at times, and the plot is pretty straight forward.
