I gave this 5 stars because it is well done and so real. As if you are experiencing the entire horrific fate. So much so, I felt faint and left the theater and head for the restroom and blacked out! I was terrified when I found myself laying on the rest room floor. Realizing that I took the physical aspects of the movie to heart so much that it caused this reaction. I have never been a person so scream or be fearful of blood and guts, but this was so well done, I felt as if I was actually experiencing everything ! So beware if you are ultra sensitive. I wish I could have finished the movie and was grateful I didn't cause a massive scene by passing out in the movie with an audience, that would have been so embarrassing.
