This movie deserves rating 5 because 50% of it is bad, and 50% is good. Bad is the scifi stuff, meaning it is shown without any explanation, details, or expected things. It just seems too extreme to be able to hide something from someone for so long time, yet ignoring it. Good part is everything else. It is very real. Canadian place, people, culture which is obvious from the beginning (this can't be USA or UK) but is all in english. Other realistic things are family problems, disease, enemies, accidents, and my favorite psychiatric hospital. It is exactly shown as it is in real life, meaning with all the usual problems we experience in our lives, with our families, and on our work. This movie, besides being scifi, is about hard work, disease, and other real-life problems. Unfortunately all such bad things except scifi part are part of our real lives. If somebody else liked psychiatric hospital part, I recommend them to watch Unsane movie, which is negative and realistic too, but more focused on mental hospitals.
