Something Hollywood should NEVER EEEEVER dare to remake since I read somewhere they're preparing a reboot of this. Fight scenes/machete gangs/drug lord/corrupt cops become the main story. Forget the rescuing brother or the Swat member's wife getting preggie subplots.. There's this one henchman named Mad Dog despite how many times his head gets smashed on the floor/walls, even a knife to the neck, dammit, he's still got lots of canned whooped ass left in him to beat the shit out of the Swat team.. Almost insane on the same level as the fight scenes in Old Boy too... Go see it.
