Raul Marques’s review published on Letterboxd:
This is what a documentary with a weak script looks like. Moselle's ability to convince the family to share their story is way more impressive than her work on the actual film, that suffers from the bad kind of loose structure and lack of guidance to the narrative. The Angulo brothers are really compelling characters, more so than the privation of almost any social interaction would imply, but their charisma can only go as far with such a messy direction. Both parents are far creepier than the vast majority of villains, although there is an effort to try to humanize them.
