This has undoubtedly been the big mistake of the film, does not tell anything, yes, we see them suffer and live with the strange and curious Aneris, which is captive and does not dare to escape. But it does not tell us much more.
Aura Garrido, masterfully represents Aneris, is perfect. No, it does not speak, it does not have an expression just in the face, but Aura does such a good job that you really lose sight of the actress to make way for a creature that seems taken out of Lovecraft’s world. All movements are of her and you perfectly see her fear and curiosity.
