Query: Full of action, thrills, and suspense. Finely woven classic kind of action film. Not to be taken seriously.

"Violent, gritty, well-photographed, and action-packed Indonesian thriller that has all the pack of a punch as a hardcore martial arts film and a somewhat realistic SWAT raid. Nothing sanitized here, folks, this is the kind of stuff British men love to see after going to the pub. One of the best and most exciting films of 2012 so far."PRO: Intense, brutal/bloody action sequences. Minimalist yet grand approach. Lacks use of CG and SFX. Made even a chance in multiplexes with it in Indonesian. Themes about teamwork and strategy.CON (Spoiler alert): Lacks some part toward the end with the elder and the brothers.
