Gangster High

Gangster High is a 2006 South Korean film written and directed by Park Kihyung.

Gangster High opened in South Korea in October, 2006, and premiered at the European Film Market in Germany on February 8, 2007. In the United States, Derek Elley of Variety described it as bleak and violent, but praised it as well drawn in all its diversity and with occasional humor by a good cast. James Mudge of Beyond Hollywood gave it a positive review Although its premise may sound overly familiar, Gangster High certainly stands as one of the best teen violence films of recent years, with Park proving that he has not lost his touch when it comes to dealing with tales of troubled youth. Hardhitting and gripping, it offers a different and arguably more convincing take on the usual themes, and contains enough vicious action to entertain as well as provoke.
