Well, would firstly like to clarify that Kaakha Kaakha is a part of a Tamil prayer and roughly translated it means "to protect". Khakhee on the other hand refers to the color of the police uniform (which is Khakhi!).Also, the Tamil film industry is rather full of purely commercial ventures , any Rajnikanth or Vijay movie would stand testament to that statement.Now Kaakha Kaakha is an EXCELLENT movie with a great soundtrack. Certainly very stunning in the final scene, especially love the ending (which is certainly unexpected!). The gore is rather too much at times, but certainly this is a great movie!
