Revenge is served raw and simple in "Bedevilled"(2010). The movie delivers exactly what it promises to us, but that is not for free. There are barbarous scenes that make you wince, and then there are bloody scenes that make you cringe, but this South Korean revenge thriller has gallons of emotions to spurt on the screen in its sad, wretched character. It carefully prepares its ground while seemingly following the typical formula of revenge movies featuring abused heroines. It continuously accumulates explosives beneath its surface as the plot progresses. And then, when the time comes, it explodes its anger magnificently like a harrowing bloody aria.
