Soo was released in South Korea on March 22, 2007, and was ranked fifth at the domestic box office on its opening weekend, grossing $795,086. In total it sold 218,314 tickets, and as of April 15, 2007, had a gross revenue of $1,275,162.
Kevin Ma of Lovehkfilm.com reviewed the film saying, "Soo's concept is somewhat successful on paper because it doesn't take the easy way to revenge. In execution, Soo is wildly uneven, moving between slow exposition scenes of plot development and raw, brutal fight scenes dominated by chaos. However, it remains a compelling and violent action film thanks to Sai's fluid camerawork during the action scenes and the performances of his actors. Special kudos go to star Ji Jin-Hee, who sheds his romantic leading man reputation to become a believable killer who can stab and punch his way out of a fight. Sai also sheds the expectations put on him after Blood and Bones by delivering an arthouse spin on a straightforward revenge film. Still, the film's ultimate effectiveness remains highly debatable."
Derek Elly of Variety.com reviewed the film saying, "A onetime killer hits the road to self-redemption by tracking down his brother's killer in "Soo," a coolly told, often brutal yarn that remains strangely involving despite its flaws. High-concept idea—a twin brother takes on his dead cop brother's identity to solve a crime he's also been hunted for by the cops—has strong remake potential. Pic itself, which bombed on South Korean release in March, is more ancillary or film week fare."
A reviewer of KoreaTimes reviewed the film saying, "Soo is a memorable film. In Korean, "soo" means water, the very essence of life. Throughout the film Soo seeks to free his brother from "han" or spiteful grudge, as well as his own soul from staggering guilt. Even the Bad Guy wishes to spare his father the fires of hell. Choi's lasting imagery of water washing away blood suggests the pervasive human instinct to survive and the desire to purge oneself of one's impurities."
