It was just over acting throughout the entire 148 mins. Akshay was good at some places, but he does not get much scope to deliver. Kareena looks hot and that is all she is pathetic for the acting part. The language of the movie is too strong and vulgar and I don't think it can be categorized as UA.
At some places I thought its a remake of Salaam Namaste which is a much better movie than Kambakkht Ishq.
