Although I haven't seen the film, your analysis is quite detailed and offers an exciting perspective on how an adaptation can diverge significantly from its source material and, in the process, lose some of its essence. It's a common situation with comic book to film adaptations, where the need to condense a complex story into a shorter format can lead to narrative choices that don't always satisfy fans of the source material.
The fact that the film has generated such divided opinions tends to happen with works that attempt to tackle complex genres and subject matter, such as psychological horror and surrealism. On the one hand, some find these dense, symbolism-filled narratives deeply engaging; others find them confusing and lacking in coherence.
It is true that sometimes, in an attempt to create something unique and surprising, creators can overload the story with too many elements, resulting in a plot that feels overwrought and unclear.
