WOW!!! You want to be shocked/jaw drop, watch this!

Rating: 9/10 (3 October 2014)

MUST SEE movie if you love films with substance and enjoy thrillers/character pieces - no A.D.D mindless action (they showed Taken 3 during the previews, seriously!??!?)
This is a VERY *CRAZY* and gripping movie. It's just INSANE. There was one scene where the whole theater just went completely silent... not one drop of sound... I think everyone just had their jaw open in disbelief, including myself.
It really blew me away and most films these days don't do that for me. I was very engaged throughout the film... you don't really know who to feel sorry for.
If you enjoyed PRISONERS, with Hugh Jackman, you will enjoy this too (yes, both films are almost 3 hours long, so if you can't sit still, it's not for you); they're both equally gripping, but it is more shocking.
I felt some 50 Shades of Grey... There is nudity and sex in the film, so if you can't handle that, it's not for you.
I have not read the book or knew anything about the film, so everything was fresh to me...
Amazing performances and excellent casting. Rosamund Pike as AMY is perfect. Ben Affleck is good. Neil Patrick Harris... Wow, that was some interesting character...
People like these DO exist, and that is what makes it frightening... Not zombies or ghosts.
This movie blew me away. The story, performances, editing....
This film proves amazing films can still be made today!!
This film is scary in a whole new level. It's definitely a movie that will leave an imprint on your brain and want to keep discussing about the film.
Highly recommended. It is a DARK film - it is a HEAVY thrill-ride experience. MUST SEE. GO SEE IT!
