Justice League
This movie is basically Avengers Assemble with DC characters...only with significantly less prequel movie buildup. In a way that makes it better, because Avengers Assemble was an absolutely terrible film precluded by several fairly good ones and a few bad ones. Justice League is an absolutely terrible film precluded by a few equally bad ones and one good one (Wonder Woman) so, whilst it isn't a disappointing anticlimax the way AA was and is about what I expected from DC, that it met my expectations is definitely not a good thing, because I was expecting to be bored out of my skull and I was.
I think Aquaman is well cast, though...well, to a point. I honestly prefer the blonde idiot Aquaman who sings rousing songs of heroism and gets himself into all sorts of silly situations, but since DC movies have to be gritty and miserable (please change this, Shazam) casting Jason Momoa was a pretty good choice.
But seriously. DC have no business making live action superhero movies. They should just stick to the animated ones. Those are almost always great, or at least entertaining, and they don't drag out for what feels like two and a half years rather than two and a half hours.
