About
You may like this if you enjoy moody, offbeat sci-fi with creepy insects, a dreamlike feel, and slow-building tension in the vein of Kingdom of the Spiders; Not for you if you want fast action or clear answers.
Pros: mesmerizing ant close-ups; eerie desert atmosphere; original sci-fi premise | Cons: thin human characters; slow pacing; vague storytelling
