From 'gosh it looks like a Cronenberg movie' to 'gosh it is his son's movie' is one step. Unfortunately a pretty long step. Indeed, it is in the combination of the very strong influence of his father's filmography with the attempt to break away from it that Infinity Pool finds its undoing. The film lacks so much structure, cohesion, and meaning that it is difficult to give it a well-structured review.
Starting with the premise, the film immediately fails to get the viewer oriented in the world it wants to tell about: are we in our reality? In an alternative one? Li Tolqa's costumes are unusual, but outside of it, is our morality that of the protagonists? The film would lean toward making us understand that Li Tolqa is a fictitious place, yet immersed in our reality. With the main characters we should consequently share morals. If this is indeed the case, the fictional reality of the film cannot stand on itself in the slightest, as it is too improbable. If, on the other hand, this is not the case, the film fails miserably in making us understand what key we should give to what we see depicted on the screen. This makes it, yes disturbing, but overall alienating to the viewer of the story. The result is too full, too confusing, too eager to provoke and disturb to have a defined identity. The use of continuous technical virtuosity also contributes to the sensation of overall overabundance of the story.
This is not to say that there were not many elements of potential interest, or that the director lacks skill and talent, but how the entire production fell short in reducing, deducting, and correcting all those elements that separate an experimental film from a messy one.
