Matt Singer’s review published on Letterboxd:
Can’t help but wonder what Cronenberg would have done with this material, but Whannell is coming into his own as a director. It’s obviously made on a low budget (takes place in a giant mega city with a population of about 25 people) and like a lot of B sci-fi, it’s much more interested in violence than in fully exploring this setting. On the other hand, the effects and camera work are definitely slicker than you expect in a movie of this size. I liked it!
