Just rented Aquaman and recorded it. I give it a solid 5 out of 10. It was pretty much a cartoon. Talking underwater, and it sounds completely normal. Water doesn't seem to slow anything down. I realize you need to suspend your disbelief for some movies, but they might as well have started some of the scenes by looking at the camera and saying, "Here's something ridiculous for ya!" There's so much bad about it.
I like him, and his personality in the movie, but just about everything else was so bad. The technology was like Black Panther, but more over the top, and underwater.
