It's like a fever dream being presented on film

Rating: 4/10 (15 April 2019)

How could I possibly encapsulate all this film has to offer better than others before me? This film has what I will call "Venom Syndrome" which means it switches genres every 10-20 minutes. It seems to have no clue what it wants to be and it also seems there were several writers tasked with certain types of scenes and it is...glaringly obvious.
Like others have said, there are several scenes where it's like watching a live-action Little Mermaid in which the "romance" is more painful to watch than Hayden Christensen harass Natalie Portman into Stockholm syndrome in Attack Of the Clones.
Then it tries to emulate Star Wars in many ways (even underwater space-battles), make a brief statement on man's environmental impact once in a while, turn Aquaman into a freaking water-bending prophecied one, introduce some gadgets that make Spy Kids look practical, Aquaman apparently exists within the Monster verse with kaiju, and can we please talk about the CHEESY armor the soldiers from Atlantis wear? Good god, it looks like they went to the value bin at the studio and took out the rejects for Tron and Super Mario Bros.
The best things I can say about this film is the cinematography is very nicely done, and the special effects/CGI is rather excellent save for some de-aging for flashbacks. The hair effects underwater are noticeably superior to any I've personally seen and the color palate is spectacular.
TL;DR: This film is a visual spectacle, but with a schizophrenic script, subpar writing, and some truly incompetent chemistry/acting it is like experiencing the fever dream of Gary Busey himself and it is not exactly easy.
