The biggest thing that surprised me about this was that it was more of a buddy cop movie, not the newly crowned King of Atlantis sequel I expected. This was Momoa bro'ing out with whomever they put next to him, with very little rhyme or reason. The normal bad guy was dumb, the ultimate bad guy was even dumber, the super anti-Atlantean weapon was dumb, almost everything Momoa said was dumb, the whole movie was just dumb.
Yeah, it's pretty much goofy nonsense. It's not offensively stupid, to me anyway, but nothing about it makes any sense.
I have trouble believing that at no point someone pointed out that having an undead lich king burning totally-not-uranium in a literal furnace to cause global warming because his city is iced over is the second dumbest evil plan ever seen in a huge budget movie.
