Just to share this, a fresh action movie with lots of silat which does make it look different
from everything else. The stunts and the knife fighting are really good, I think it's
like what Ong Bak was for Thai martial arts.
ALso I read that the main actors trained with Malaysian special forces for
many days and that they were treated like soldiers.
