I absolutely loved it. 4 hours went by like 5 minutes. I was engaged in what was happening on the screen the whole time. The characters had more development, it was interesting to see their motivations and relationships with other characters. The square format was a choice, considering that this came out online and not in theaters, but halfway through it was not as jarring. All in all, a great movie. Of course, it's not perfect but it was what I wanted from a Justice League movie
