Mind-numbing. Build up is slow and gradual with a lot of trance-like, hazy sequences but once the second half rolls in, it turns absolutely, deliciously wicked and brutal in a real hurry.
The lead actress has done an absolutely fantastic job in her role, and Sean Pertwee shines in his antagonistic sleeves. Be sure to grab the DVD as soon as it releases because this film is a must-watch. You can thank me later.
Highly recommended.
