How can you put Batman, Wonder Woman, Superman, Aquaman, Flash and Cyborg in one movie and yet make it this horrible?
WB just want to milk money of the Avengers types and that's why they rushed with this movie. Audience never connected with Ben Affleck's Old Batman and the newbies Cyborg and Flash.
Avengers succeeded because audience was made familiar and connected with the characters by 5 movies beforehand. That's why that grand teamup felt special. Unlike this rushed, illogical one.
