Metin Seven’s review published on Letterboxd:
At the start of Upgrade I had my doubts if it was going to be good. But once 'STEM' was introduced, it became quite a fun ride.
My wife and I had to laugh out loud when STEM took over control of the first fight. Brutally hilarious.
I'd call Upgrade an entertaining wink to RoboCop, Terminator 2, The Matrix, Blade Runner and... Knight Rider. 😁 The futuristic props and decors were quite cool, and since I saw the Quarry series I've got a soft spot for Logan Marshall-Green.
Upgrade's ending was also original, being positive and negative at the same time. I wouldn't be surprised at all if a sequel is already planned, and I hope it will be at least as good as this one.
