The best Sci-Fi/Action movie in a long time! First of all the less you know going in the better, so I'm not going to spoil anything. This movie verges on a 10, but gets a 9 from me, for what I believe could be boiled down to budgetary restrictions. Upgrade feels a tiny bit rushed, but otherwise it's a feast for your eyes. The story is bulletproof and the twist is almost unpredictable and more so you are surprised at what writer/director Leigh Wannell achieved with the small budget he was given. He crafted a stunning world full of interesting concepts, all complementing the overall story
All of the former mentioned things are spectacular, but they all fade when compared to the camera work and masterful editing this movie provides. If I would have to describe watching Upgrade, I would say it's a roller-coaster with the perfect buildup and execution.
It's really unfortunate Upgrade did not have a large studio behind it. That must be the reason people did not see this movie as I refuse to believe people just disliked it, but then again maybe the film would not have been as good as it was.
