Rich Hoppes’s review published on Letterboxd :
My expectations were a bit off for this movie. I was expecting a straight up horror movie, probably because it is written and directed by Leigh Whannell, but no worries. My fault for not checking the genre beforehand. Having said that, I really enjoyed it. It's an interesting story, has great visuals, really good acting...and all on a $5m budget. Very impressive.
