Rare sub 5 score for me. Art for the sake of art.
Empty. Takes a theme/concept and just tries to justify an "art" film or "psychological thriller" out of it. And this is where the crux lies...film has no idea what it wants to be.
Writing around a Mcguffin. The writing doesn't carry the story. So the director just tries to create an almost Hitchcock paranoia to the film. Mangles all the cuts together. Flipping in and out of time and scene with no real direction other than to artificially create confusion. You suspect the director is trying to show mental health issues by way of random scene cuts, but ultimately fails.
Anyway, at about the 1h30m point, the film way overstays its welcome, delves into some over the top "artistic" representation of mental health issues, and just loses any semblance of crafting anything out of the previous 1.5 hours. It almost feels like the writers and directors give up.
What is really troubling is that the movie focuses on a current overly dramatic trauma as being the cause of mental health issues rather than trauma during formative years. The main character obviously has mental health issues throughout, but the writers choose to completely ignore what formed these issues in the first place.
And finally, the ending is just devoid of humanity.
