I personally loved this book. It was one of my favorite horror film when I was a kid and I never knew it was a book until I stumbled upon it in a Savers!! So I was so excited to read. 
I felt like it was slow in the beginning, especially coming from watching it as a quicker film, but it was so interesting really learning about the characters traits in more detail and hear them explain these horrific experiences their going through. The characters are… interesting, but I thought were written well for their rolls. Like the way the all handle this situation is super interesting and sometimes sad.

Overall I think it’s a great read.
