Infested

This French filmed also titled 'Vermines' is a fun survival thriller; you will have to watch with subtitles if you don't speak French.
The film has a really cool and unique setting, probably somewhere most people outside of France didn't know existed or have little knowledge of life in their social housing; also an absolute eyegasm for architecture fanatics.
If spiders really frighten you, this film will give you a heavy shock of creepy crawlies, which are a metaphor for xenophobia.
Highlights are the great acting, camera work, and soundtrack score.
The film is scary, with jump scares and a claustrophobic atmosphere, but we would say it could have been scarier; unless of course you have arachnophobia, this film will terrify you.
The relatively unknown cast features Théo Christine, Sofia Lesaffre, Jérôme Niel, Lisa Nyarko, Finnegan Oldfield, and others.
*Trigger warnings: animal death, arachnophobia.
