Nakamura Genji's rousing "V Madonna Daisensou" is certainly not for everyone. With its ultra violence, intense drama and gritty storyline it seems almost like a throwback to Toei's low budget "Sukeban" exploitation films of the 70's. As others have noted,"V Madonna" definitely takes its inspiration from Kurosawa Akira's landmark "Seven Samurai" but also is heavily influenced by Toei "Pinky Vionece" films like "Sukeban Guerilla". Its raw intensity definitely is riveting especially when the "Madonnas" are being tortured by the sadistic teenage "Yaguu". Yet one can't help but cheer these gals on especially when they unleash their full "female fury" upon their opponents towards the end of the film. The "Go For Broke" reference actually refers to the legendary Japanese-American 442nd battalion of World War II who used it as their inspirational motto (the 442nd were the most decorated soldiers in WWII). It's used here probably as a casual reference to the Madonnas "do or die" attitude. Some might see some resemblance to the "Sukeban Deka" (I think this film predates the series). If you like Toei's "Pinky Violence" films of the 70s or female revenge driven films like "Gonin 2" then this movie is for you.
