KANK is a very poorly written and directed movie. The plot is weak and the acting is a repeat from previous movies we've seen of the stars. If you ask me the movie seemed to be a rip off of two movies, hum tum and saathiya. Dont waste your money or time with this piece of trash.
I think its good for both the spouses to have some harmless flirtation outside marriage...keeps the flame alive. Of course the other spouse should not know about it...can be your little secret...You should after all feel good about yourself...and in turn can be good to your spouse. I am not in any way preaching unfaithfulness....
Trouble is people do often cross the limits.
