Some really astounding sound effects.

I'll admit, I watched this wholly because of Javier Botet and his amazing amility to play distorted villains.

Overall, it was quite good. But what made like 90% of this movie (besides Botet) is its AMAZING sound effects. Especially the sound of the monster itself. I watched in headphones and was quite impressed with how they managed to do the sound in this film.

7/10 from me = 3.5 for Javier Botet + 3.5 for SFX.

Nolan, I love you forever!
