"Elite Squad: The Enemy Within" is a an all-guns blazing, high-octane thriller that maintains its intensity from start to finish. In this sequel (a rare improvement on the original), director José Padilha gives a brutally honest depiction of the far-reaching corruption involved in the fight against drugs and crime in Brazil. It definitely isn’t for the faint of heart. For this installment, the film benefits from much-improved storytelling, resulting in a truly engrossing experience. If you can handle the bleak images, I’m sure you will be on the edge of your seat.
