VS-634 - Abused Female Warrior Naraku no M

I enjoyed the previous 'Masochistic Warrior' entries featuring Miku Fujioka/Miki Hayama and Kanako Fujimori/Yoko Yazawa, and since I'm a fan of the actress Okazaki, I had high expectations. Unfortunately, the final product is a letdown. First off, the SM flavor is extremely weak, and it's filled with pointless acting that feels like a low-budget Nikkatsu Roman Porno. Neither Okazaki nor Mami Ogawa are utilized well, and the character played by Maiko Yuuki lacks any charm. It's just plain boring. Since this is the first of a two-part series, I'll hold out some hope for the sequel, but this left me so disappointed that I'm hesitant to even buy the second part.
