Itโll give you a headache.
Youโll never know the answers to any questions youโll have.
The ending is intentionally upsetting.
The title is symbolic, so also intentionally misleading.
Extremely slow paced and uses dreams as โforeshadowingโ, so original.
No character development, no character arcs. A lot of โwhy would he do thatโ and the writer/director clearly doesnโt know the answers.
