The book does depict ancient drawings of sexual positions, but it also contains verses significant to the sensual pleasures of posing, love, family and other aspects related to the pleasures of life. In the modern Kama Sutra material, the verses may not be included or may be more geared towards sex than the ancient intent. If you take the book of Kama Sutra and use it to enhance your intimate life instead of using it as a sex manual, you will find the sensual pleasures that the Indian Hindus were guiding you to. It's not about the sex, it's about the Hindu goals of finding lifes pleasures of which intimacy is one. That is the Art of the Kama Sutra.
