I thought this was a very well made film, which drew obvious parallels to Saw in the opening scene...but thats where it ends, its far from a Saw rip off as previously mentioned, it does challenge your sense of morals, the "baddie" is extremely well acted as is our heroine and the characters are a lot more than one dimensional killer/victim types. The atmosphere is realistic, and this film delivers a lot of award winning aspects.
As for the films contents, I really hated this sick guy, and wanted to see him punished, which brought out more emotion than your typical slasher flick, which most I term comedies due to their predictable outlandish villains.
There's none of the annoying stereotypical bad guy gets hit by car, shot by arrows, hit by axe and still comes a chasing scene that you find in the usual run of the mill films of this ilk.
I do recommend this film for everything that you can recommend a film for, except one thing... it should never have been made, you would have to be real sick to appreciate any entertainment value in this film, its gritty and a little too close to the bone for my liking...and I assure you I'm no prude.
Well done film makers excellent execution, but make something a little more pleasant next time, whats wrong with you !!
