This was a great movie, even better than I expected. It helped that Amber Heard was there to play Mera, and of course, Aquaman's arch-nemesis, Black Manta, was one of two villains in the film. Either setting up for the sequel or the next Justice league movie.
I still wish they'd cast someone who looks more like the image of Aquaman, but Jason Momoa owns this role, the way Robert Downey Jr. became the one and only Tony Stark.
Hopefully this is more of what can be expected from a DC Universe movie.

This is one of very few comic book movies that not only doesn't shy away from some of the crazier things in the source material, but actually relishes in it proudly, making it quite self-aware. While some may not think that a good choice for the big screen, I think it makes for an entertaining movie. It was also a beautiful film, with enough colors and wonderment to make up for the lack in the first few movies of the DCEU.

Having said that, I felt there could've easily been two films made with what's presented here. I liked both main plotlines, but neither really had time to breathe being crammed into one.

Maybe this was explained and I missed it, but where was the Atlantian motherbox kept if not actually inside Atlantis? I ask because a big deal is made getting into the city in Aquaman, whereas in Justice League he just happened across it.

I personally would've liked to have seen more background of Atlantis society and history, to get a clearer picture of why Arthur's mother had to leave in the first place, amongst other things. So she didn't want to marry the king because...? When we see Atlantis it appears to be a thriving utopia, so what was the problem? If the city had fallen into disrepair, and the people depressed/dejected, then the corruption and need for change could be clearly felt, making Aquaman's rise to meet his destiny more understandable, with that contrived war between Atlantis and the surface world being the catalyst.
