This movie is going to fail so badly. Its amazing Wb is still going for it.
Maybe the mamoa factor will happen again and get women out to theaters like for the first one. You also have amber heard in it whom they'll most likely not want to support.
The productions been a complete mess from the sounds of it. Apparently James Gunn called it unwatchable. Hostility between mamoa and heard. There's probably zero enthusiasm from everyone involved knowing the universe will be headed in a different direction after their film releases.
WB fucked themselves for a whole decade before finally doing what we've been saying to do for years and get a producer(s) to oversee every film and make a more connected universe.
