Justice League is cynical.
Don’t get me wrong, the Marvel films are cynical too. It’s all cynical. Hollywood is a cynical industry.
It strikes me, however, that Justice League is an example of the cynicism of Hollywood gone horribly awry.
That’s not to say that it’s terrible, or even that bad. It’s certainly far better than Batman v. Superman and Suicide Squad. But for all their faults, those films at least presented a consistent worldview. Justice League feels tonally consistent, at odds with itself, in unnatural ways.
