So I bit the bullet and saw Justice League anyway because it was essentially free and it still wasn't worth the cost of entry. They went from a fundamental misunderstanding of why The Dark Knight Trilogy was successful to a fundamental misunderstanding of The Avengers. Ben Affleck phones in his performance, Ezra Miller is fucking cringe worthy and everything about Cavil's Superman in this felt painfully forced, like everyone involved simply threw up their hands and went "see we can do what you want. He's happy now, don't you like it?" This was a far more cynical take on the material than MoS or BVS to me and frankly, it was insulting. Man of Steel and BvS at least had balls. This was a live action Hanna-Barbera cartoon. This is what happens when you kick-off a cinematic universe based on the demands of your shareholders rather than actual interest in the material. Say what you want about Marvel, but they, at the very least, actually like the material and actually give a shit on some level.
When Jason Momoa gives the most believable performance in a movie, you know you're in trouble.
