That spiral staircase scene was so cool, talk about something literally hypnotizing. Although that’s an odd opening, I think the visuals are the only thing worth talking about in length with this film.
With possible influence on Argento, the set lighting is oddly vibrant and seemingly intentionally out of place. It adds depth to dark corners and an already impressive set piece.
It’s an all around, really solid giallo film. There’s some dated cheesiness for sure but nothing unexpected for the time period.
