If a movie about a snowstorm could be made without snow, this would be it. Seriously, I don't think the director has ever seen real snow in their life. The landscapes depicting the blizzard look like cheap sets from some old film, and the "snowstorm" is more of a failed special effect than an actual natural phenomenon.
Snow, as a central element of the film, was completely unconvincing: either it was poorly rendered or just entirely unrealistic in its behavior. I don't understand how the director could overlook such important details like the texture of snow or how it actually behaves during a heavy snowstorm. In a real blizzard, everything looks different - the wind knocks everything over, snow piles up in heavy layers - but here, it's all fake.
It's not just a minor detail; it's the core of the film. If you're making a movie about a storm, you should at least pay attention to the snow element instead of abstractly approaching it. I kept watching and wondering how anyone could detach from reality this much.
Overall, the film was a letdown. For some, a snowstorm might just be a bunch of white patches on screen, but for me, it's not like that. Even if the whole plot were perfect, the artificial snow would still ruin it.
