It wasn't horrible ...

Rating: 6/10 (29 March 2018)

I've definitely seen superhero mashups be worse. Mostly this just felt like a not-as-good-Avengers.
The thing with superhero mashups is that there isn't a lot of time for character development. Characters can have arcs but they have to be small ones so we need to know the characters beforehand so we can care about them. So DC messed up in that we only really knew Superman and Wonder Woman. We knew a little about Batman from the Batman vs Superman movie but not really. So that's half the characters we have absolutely no history with when this film starts ... that's a lot of gaps to fill.
Justice League tries, but the characters all feel flat even the ones who previously had stories and personalities. I'm not sure what happened but we get zero development, zero personality ... just deadpan performances all the way around.
Add to that, pretty terrible CGI.
Then there's fact that Superman makes the rest of them seem useless. I thought the Flash was supposed to be faster than Superman? I thought Wonder Woman was supposed to share Superman's level of strength? Batman seems especially useless in this film ... like he gets them all together but he's old and clunky in his suit and can't fight worth a damn.
Aquaman I just don't get. He lives in the water ... there's some jokes that he talks to fish ... he's strong? But we don't get to see him flex his water muscles, he does most of his fighting on land, he's got his trident thing but he basically just uses it as a pitch fork. So I don't get it.
And as soon as Superman shows up it looks as though he could've single-handedly taken out the big bad. Like he wasn't working hard at all which made the defeat of Steppenwolf extremely unsatisfying.
So yeah ... not awful but just kind of meh.
