Suspenseful, Sad, Horrifying, Fun!
I feel like the movie would've been more well received if it went in a different direction. The plot had several ways it could've gone... but any other way wouldn't have been as fun! It was visually stunning, the music is great, and the sound design had me feeling anxious (almost) the entire time. Towards the end I kept asking myself, "It cant get any crazier than this, right?" :and every time, I was proven wrong.
Its very rare to see a movie this mainstream and with such a high budget (compared to other newer films within the same vein) to get as extreme as it did. No one is ever forgetting this movie.
P.S.
Do not plan on eating while watching this movie. I do not have a weak stomach. I can usually eat while watching gross out/body-horror/gore films; but due to the sound design, this movie was different. A few minutes into the movie and only half way through my burrito, and I had to stop eating. You have been warned.
