Spoilers:
Whilst I wouldn’t exactly call it a great movie, it is much much better than the original justice league. Four hours was definitely way too long for this kind of movie and it does drag in some areas. There were also too many slow motion scenes. Why. However, I did like the risks it took, such as showing Darkseid and the Martian man Hunter, some of the risks weren’t that great, such as mentioning the anti life equation, if there were more movies and more build up then it would be warranted, but obviously it’s not. Since it’s not canon, and frankly, since I don’t care about the dceu continuity anyway, this is a movie I’ll probably never watch again.
