Baz’s review published on Letterboxd:
Kim Jee-woon seems amazingly astute at the helm of such an intense and taught, cat-and-mouse thriller. Each scene is perfectly crafted that reaches further than you'd expect, but does so with such eloquence, which, juxtaposed with the violence, exemplifies Jee-woon as a master of his craft.
I'd put off watching this for too long for no real reason, yet once it starting I was hooked from the off. Ostensibly a revenge thriller, that's not in the same league as your average revenge flick. Staring Byung-Hun. Lee and Min-sik Choi, as the 'Hero' and 'Villain' of the piece, together they are a perfect match for one another, so relentless in their performances, I'd be hard pressed to compare with any other performances I've seen recently in similar roles.
Once the film had finished, I quote from Harvey Dent in 'The Dark Knight' came to mind -
"You either die a hero, or you live long enough to see yourself become the villain"
A hugely entertaining modern horror, with so much to absorb, it's one I'll be rewatching again, that's for certain.
