Ki and Ka is a movie you cant watch even on your TV screen, going to theatre is a big deal otherwise.First of all, the lead pair looks so incompatible. No where in the trailer are they able to create sparks. Kareena is old and Arjun any which looks so horrible. Music is good, but then you can hear it on your phone. I would not recommend to watch this movie, for its going to be yet another drama flick, full of overacting and not-so-appropriate story line.
Rather go watch London has Fallen or even Zubaan trailer looks great.
