Britt W’s review published on Letterboxd:
Upgrade is fantastic. It's gritty, humorous, emotional and action-packed. But most of all, it's a great story with excellent direction from Leigh Whannell and exceptional acting from Logan Marshall-Green.
The action sequences are simple (on paper), yet so outstanding because of the topnotch camera work AND because the fight choreography is intricate & magnificent. There is tons of blood, which i wasn't expecting, but damn it is SO GREAT. And ultimately, the finished product is awesome from beginning to end.
My only frustration with the film is that the ending felt way too abrupt. It may be that I just wanted/needed more BC I was having such a great time. But that's just a testament to how great this movie truly is.
