Reviewers complaining about humans being able to breathe/live in Atlantis at that pressure etc are forgetting the basic premise that this is a superhero movie, not a documentary! This is a good superhero movie, Jason Momoa providing a solid performance as the action hero with a conscience, punctuated nicely with dry humour, with great backup from Willem Dafoe, Nicole Kidman, Amber Heard and even Dolf Lundgren. Plenty of action sequences, and enough character development to care about the principal characters. I went into this movie with low expectations and was pleasantly very surprised. Give it a try, it's well worth it.
