Whannell's high-tech detective story has plenty of action, but lacks a good mystery
it's a goofy fun...even in its most self-serious moments, Upgrade is more fun to watch than a lot of low-budget sci-fi movies we see in festival or VOD settings; a good-natured film that will never bore you
a pure adrenaline shot of sci-fi body horror thrills.. a film that is never dull and will always have viewers eager for the next big event
