Ninja Assassin (2009)

This is an okay movie. Raizo (Rain) was kidnapped as a child, while living on the streets as a orphan. He was taken by the Ozunu Clan, a secret society that raises abandoned children and trains them to become lethal fighters. Their attack style is swift and almost supernatural. When his girlfriend (Anna Sawai) is executed after trying to escape, Raizo leaves and vows revenge on the ninjas. In Berlin, Mika Coretti (Naomie Harris) discovers financial transactions proving the existence of the gang and is rescued by Raizo from an attack.

The film is good, but the gore is too extreme. The Wachowski brothers, famous for the Matrix trilogy, were the producers. Rain is a pop singer and actor from South Korea.
