I really enjoyed Aquaman, even though I often skip superhero movies since they all look alike after a while. You have to go into it with the expectation that it follows the same formula as most other superhero movies. What sets it apart for me are some incredible underwater scenes. Parts of the movie were fun adventure, parts were visually spectacular.
I wish they made Orm, Aquaman's half-brother, more complex instead of a one-dimensional power hungry leader. I thought he had some good points about the surface dwellers polluting the oceans, and throwing the trash back up on the beaches was a good move on his part. He didn't have to be a "villian" if the writers had given him a cause to work for.
