It starts off pretty well: a 1st part where you can feel the applied and sincere homage to the giallo ("Suspiria" at the top of the reference), beautiful vintage aesthetic, soundtrack in tune, pretty murder scenes, suspense, and we find ourselves thinking of holding the long awaited great neo-giallo there.
Unfortunately, the rest is less breathless cause dragging the film into a somewhat painful gore overbidding and a more agreed upon resolution of the plot.
A semi-success of which we will keep in mind the very correct staging and the beautiful first half.
