Except for the scenario of the ending (not its outcome), the movie is almost perfect. I found the acting decent, and while the characters, especially the main character, are not very likeable, I found them very true-life. There is the main Vlogger, then his sidekick, and then his secondary sidekicks, it's a well-oiled machinery that generates money with needless waste of time. Behind that there are more or less normal people with the right nose for their business.To deliver more thrills, the protagonists agree to an ultimate escape room experience in Moscow, and this seemingly goes very very wrong. I will not spoil the movie, but one who pays attention always gets a little hint what's going on. The pacing after a rather slow but entertaining introduction of what a Vlogger's life would be (I liked this part very much), the thrilling game changes into, what we wcould call it, a Russian version of what was to be expected. Fast and brutal.There is no flaw of any kind to be found until the very end. Which is, as I mentioned, not as carefully arranged as it should be, but aside from that, it is very reasonable, as any other reaction and decision during the whole scenario. Put yourself into such a situation and you may understand some reactions easily.I have a theory that many reviewers here did not really follow or did not want to understand the movie, as it (intentionally) mimics (partially) some mainstream Horror movie series of the near past and makes its own story from their origin, in a way like "One Cut of the Dead" (which was a bit more funny, I have to concede).
