Todd Russell’s review published on Letterboxd:
Old buildings, especially mental hospitals have an inherent haunted vibe to them. Add in workers roaming around in protective quarantine suits -- don't want to breathe in the asbestos -- and a single high E note (I think that's an E) on the piano? This creepy atmosphere setup for a film involving renovating an old building crawls. It doesn't take long for this spooky atmosphere to test the mental strength of the workers.
Creepy, haunted, voices as the workers walking around the empty building ... yikes. Good screams and scares dial this one up. I wasn't as excited by how it ended, but enjoyed pretty much everything else. Recommended.
