Sally Jane Black’s review published on Letterboxd:
Memory plots can be difficult to render effectively, knowing what to reveal to the audience and what not to, making the blurring or vacant spots in memory cinematic, or simply finding new ground in tired old tropes like amnesia. Even the most heralded depictions tend to bore me--coughMementocough--so it was somewhat surprising that this little hazy-memoried giallo was so intriguing to me. It doesn't really break any new ground--and the ending is awfully rushed--but it maintains the mystery well.
(As an aside, I just glanced at the poster over there. What a ridiculously over hyping tagline. I love it.)
The most notable feature of the film are the eerie landscapes and the flashbacks to the strange science fiction in the mind of the protagonist, the bizarre moonscape suffering of a lost astronaut. The isolation, fear, and emptiness evoked in those scenes is vastly more terrifying than anything else in the film, even if they are presented as fake even within the context of the film. It's a glimpse of the pain inside the protagonist's mind as much as anything else, and that makes it that much more affecting.
