Sibyl - Labirinti di donna

I can't recall seeing a film with so many good and great elements: cinematography, acting, a good deal of great dialogue, that was assembled into such a let down of total experience. It is like observing a kid who is smart, has everything, goes to he best schools -- yet goes nowhere in life.

I don't know where this project went wrong. Was it deep flaws from the beginning and they went ahead without resolving them, or was it some kind of creative fight in post production, perhaps about comedy vs drama as the goal in editing?
