I actually have two problems (ok, not problems but things that bug me) with this movie - the acting and the very familiar and formulaic story setup. Acting is common issue with all Bulgarian productions with some rather rare exceptions. If I happen to watch Bulgarian production that is dubbed in English for instance it instantly gets better. So, here we get more of the same - stiff, emotionless, declarative. Deyan Donkov gives a performance above the others. Lead actress tries, but it is obvious she needs more experience.
The story tries too hard to be dark and provocative but it cannot steer away from the million other movies exploring lost souls taking the wrong road, hanging out with the wrong people. During some scenes, it looks even forced. Still, there is a nice twist midway through the movie which surprised me and gave the movie a little bit of own identity and fresh perspective only to lead to cliched final at the end. Not great, but definitely not terrible.
Camerawork and editing, along with the soundtrack is pretty much alright (especially building around old albums of Rammstein.
For a Bulgarian production, though, it is one of the better ones for sure, comparing it to other new tv series or movies, it would get a solid 8.5/10 over the others. My score is given based on comparison with all movies I've seen, and I think it is a fair one.
