Michael Darcy’s review published on Letterboxd:
Choi Min-Sik has somehow managed to match his performance in Oldboy as a sadistic serial killer who kills the wrong woman. Director Kim Jee-Woon has crafted maybe my favourite revenge thriller of all time, he shapes Lee Byung-Hun into the physical embodiment of relentless vengeance.
From the first 10 minutes I was completely gripped. Strap yourself in strong bloody violence awaits..... and a bit of poo.
