I honestly believe this tops The Exorcist.

Rating: 6/10 (2 February 2011)

As I'm typing this, I'm just finishing up Orphan (2009), a beyond horrific tale of a seemingly young & talented 9 year old Russian girl, who gets adopted by a young couple who's suffered a miscarriage among other rifts in their marriage. Their decision to adopt Esther (the girl's name) seems like a blessing in the skies, until problems with the kids at school and even her new brother make Esther show her true colours gradually more and more.
I'm going to be honest with you, creeped out would be an understatement for how I feel right now. Esther's demeanour, her actions, everything about her just sickened me to my core, I never knew a fictional character could ever possibly be this evil. Evil! And I don't say that word lightly. Not only is this a horror film, it's a psychological thriller, at best. Plus it doesn't help how Esther is tormenting and manipulating the very family that took her in throughout the movie.
I was amused with The Exorcist (1973) for the most part. What seemed appalling and barbaric back then seems like child's play nowadays, and I can safely say Orphan is this century's Exorcist, hands down.
