Gotta just echo everyone else, saw this movie, was surprisingly impressed with how fun it is. Serious enough for the story to be good but light-hearted enough that it isn't an eye-rolling awful "dark like Batman movies" movie. I think they deliberately tried to make certain things a bit hammy to give it a fun tone (shit like EVERY time a villain spoke the BGM had that 'dun dun duuuuuuuun', which I fucking loved) and I thought the action was pretty awesome too.
Also, Julie fucking Andrews was the voice of the giant tentacle sea monster thing that Aquaman befriends when he claims the trident at the end lol
