Who said it had no story? The story is just trite. The acting is mediocre. Most of the jokes were corny. The characters were flat. I mean outside of building towards a possible sequel, Black Manta didn't even need to be in he movie. They used cheesy plot devices like explosions as segways way too much in the movie.
I'm the one of the people who said the movie is enjoyable, so I'm not just hating on it, but I don't see why you're so pressed to act like it was a perfect movie when it was clearly very flawed. Even most of the people that really like it admit that. You're the only one running around acting like it's the greatest thing ever.
