If you have read the book, then you will like that movie did not tried to "improve" or "rethink" the original story, but stayed quite close to original, sometimes quoting parts of the book's text entirely.
Cast is fine. Don't let the sucky trailer full you, actors are playing fine and their characters are quite believable (except for maybe, Litvinova, but she has around 30 seconds on screen, so it does not matter).
Visuals are good. Not great, but good. Its "slightly better 90s", with slightly more human bandits, and slightly cleaner streets.
Sound is fine, and music is even good enough to wonder about buying a soundtrack.
.. but. There is always "but", and in this case - you MUST have lived in ex-USSR 90s, and you must speak Russian, to understand the movie. It's very tightly rooted into post-soviet discourse, and without "cultural references" (c), i am afraid, the movie will be hard to grasp on.
alternatively, if you have ever wondered about, or experienced altered states of consciousness, you might find it fun ;)
