I thought the opposite. I thought that based on the Batman v Superman backlash that Justice League was treated unfairly.
To me it is and always has been Zack Snyder. They picked the wrong man for the job. He made two huge mistakes in my opinion:
- He tried to make everything dark and gritty, like Christopher Nolan's Dark Knight films. What works there for that character doesn't work for an entire universe.
- He bit off more than he could chew and tried to cram far, far too much material into single films. I can appreciate his enthusiasm, but he ended up over-complicating everything he touched.
And the proof is in the pudding. Their most successful films have been those that he has had little to no involvement with, Wonder Woman, and Aquaman, coincidentally, two of the lesser-regarded names in DC's universe to that point.
