If Shane was a lady, he would be Geum-Ja from Sympathy For Lady Vengeance. It's a weird, gorgeous movie that's definitely got its flaws and is still one of my favorite movies ever. Directed by one of my favorite directors, Chan-Wook Park (He did Oldboy, which you're more likely to have seen) this is the third movie in his 'revenge' trilogy, a series that explors the concept of revenge, the way it affects the people who seek to get it, and whether or not it actually works for them.
And everyone should watch it. Seriously.
And I tried embedding the trailer in this comment like three times, but it did not work, so check this shit out.
I mean and we all know Shane would look hella sexy in that red eyeshadow. Please. He's Cillian.
