It's not surprising to learn that Chuck Norris made this series as a tribute to his brother who had been killed in Vietnam. He really gave all that he had to these films. It may be manipulative but damn is it ever satisfying. The villains are the kind of loathsome scum whom you JUST CAN'T WAIT to see messed up in a variety of ways. And the good guys are fleshed out enough as characters that you do feel bad for them, and want to see them get their revenge.
As one can guess, this is a prequel to the original "Missing in Action" film of 1984. It shows how Chucks' colonel character, James Braddock, was shot down and captured during the war, and the tortures that he and his men are obliged to endure for the next several years, even after the war has basically ended. The sadistic colonel in charge of his work camp, Colonel Yin (Soon-Tek Oh) acts like a dictator, and just when you think you can't hate this guy any more, he ups the stakes yet again.
With Lance Hool taking the directors' reins, this proves to be a high old time for the action junkie, underscored by the genuine poignancy to be found in stories about prisoners of war. This is exciting much of the time, with kick ass battle footage, lots of explosions, lots of gunfire, and some breathtaking scenery. Chuck is a formidable hero as always, and Oh is a deliciously evil bad guy. Lending strong support are Cosie Costa, Joe Michael Terry, and especially John Wesley as the ailing Franklin. Steven Williams is good in an initially unlikable part as a captain eager to cooperate with his captors in exchange for better treatment. It's also cool to see hulking screen heavy Professor Toru Tanaka and "Ninja III: The Domination" villain David Chung as two of the guards.
All in all, this is solid entertainment, complete with a high body count and never ever boring.
Eight out of 10.
