It is the most absurd comedy disguised as a "horror" film.
From the moment I saw the dive equipment (biopsy dart) sinking to the bottom instead of floating to the surface I got an idea of what I'm into. Little did I know, as the level of human stupidity and plot craziness raises throughout the film till the very end, from flying self-replicating sharks to bomb shells in Siene triggering street floods.
This is what you get for delegating script writing to ChatGPT. Sadly, I was sane and sober watching, otherwise it would be a 5* show.
