Fucking Phenomenal.
This entire film had me on the edge of my seat, glued to my screen, the story builds up so god damn well and I couldn't have enough of it. So far, this is definitely the most terrifying and gruesome movie I have watched and, boy will it be hard to top this one. The acting in this movie is also impeccable, I genuinely forgot that these are real people putting on a show at times. Overall, I personally believe this is one of Fincher's greatest movies and is well deserving of 5 stars, if not more than that.
