Ki and ka is basically a romantic movie for a couple and it is story of the couple who are differnt from the other couple. The movie is entertaing but the plot or story line of the movie is not as good as we thought. The movie is little bit of boring some time and not even upto mark.
Mean while the acting of both the actors are good. Kareena kapoor as sweet as always and arjun kapoor has shown the little bit of other side of his acting.
The casting and the direction of the movie is good. So for me its an avg movie and you can also say that a one time watch movie and diffenatly for a couple.
