It’s stylishly put together and reasonably compelling, at least so far. There are some striking visuals, and the lead (Clovis Cornillac) has a nice physicality to him. The plot is not particularly crystalline, but the limited color and light palette and particularly the sound design lend the movie a nice distinctive aesthetic. Being French, there is also a dash of nudity, and a distressing sex scene that is hard to parse.
The overwhelming aesthetic is that of a survival horror video game. But it’s not bad. I’d recommend a rental if you like strange non-Hollywood sci-fi.
