Oriana’s review published on Letterboxd:
Clearly influenced by Cube (1997), but I'm not gonna compare them.
El Hoyo had an incredible potential with its concept, and I think it was wasted by treating it kind of superficially. I was completely hooked the first half of the film, but in the end I just didn't care what happened anymore and I think that the same conclusion written differently would have made a great impact.
Could be recommended to people looking for something different - but man I'd recommend Cube 20 times more than this.
