Batman forms his league comprising of Batman, Superman, Wonder Woman, and others mentioned above, so that they can stop Steppenwolf from getting the boxes and destroying our planet. Can they learn to work together in time to stop the threat or will they fail? Will the team bring hope again? Seeing this may answer that for you.
Overall I was disappointed the most by the characters of this film. Aquaman wasn’t portrayed as King of Atlantis but more like just a dude who has special powers. While The Flash was funny, it was mostly by him being in the presence of superheroes and him showing us why he shouldn’t be there. The laughs were more about him being pretty much a coward. While I don’t know much about Cyborg, he was the most level headed one of the new characters. His character arc is probably the best option, yet his character seemed pretty mechanical. (No pun intended.)
The film’s most exciting part for me was a side scene where we see the Amazon’s defend one of the three boxes in question. The Amazons are just so fun to watch. I wish I could have said the same for the rest of the cast. I’m still feeling the disappointment.
