[Sympathy for] Lady Vengeance

I finally saw this movie. Like Oldboy and Sympathy for Mr. Vengeance (the first 2 films in the trilogy), it's a tale of convoluted revenge for past injury.
The Plot: our herione, Geum-ja, has just been let out of jail after 13 years for the kidnapping and murder of a child. 13 years sounds kind of short. But Geum-ja was only nineteen at the time, and confessed her guilt right away. More importantly, she was a model prisoner, always going to bible study and doing nice things for the other inmates.

But as we learn very early in the movie, the "angel" image that Geum-ja projected in prison was only an act. She's been planning revenge for every moment of those 13 years. Learning why a confessed killer would want complicated revenge, and on whom, is the unfolding mystery of the movie.
Overall the movie is pretty good. I'm proud to say that the other young men renting this house found it "very disturbing." But it's not great, and not even as good as the first two in the trilogy. The problem is that it eventually delivers a real villian, and with it a tidy and satisfying Hollywood ending. Oldboy and Sympathy for Mr. Vengeance let us understand the motives behind their revenge stories without making us cheer for their executors. So in that respect, Lady Vengeance is a bit of a sellout.
But it is atmospheric, and so I've been enjoying the soundtrack.
