mosquitodragon’s review published on Letterboxd:
Basically, Leigh Whannell just came up with a corker of an idea with the premise of Upgrade. From there, he has produced a film which executes on this premise incredibly well. The action scenes are exciting and novel, and he uses humour really well to enhance the effect.
I had hoped for a bit more virtuosity in the realm of plot but that's a slight criticism, really. Upgrade is a movie any fan of sci-fi action thrillers should watch - I loved it.
