There are so many things wrong with this movie. The acting is mediocre. The script feels like it was written by a 12-year-old boy. The CGI is inexcusably cheesy. The plot is not compelling. The jokes aren't funny. They kept explaining things that I don't care about. Ocean Master. Trident of Atlan. Robots in ancient Atlantis. Blah, blah, blah. So. Much. Exposition.
I have hated the last several DC films, Wonder Woman being the least terrible. This one is officially the worst. If you want something about Atlantis, the Disney one was way better.
