Suraj (Salman Khan) is a rich playboy who goes from woman to woman. When he meets Komal (Twinkle Khanna), he falls in love for the first time. Just as he has finally convinced her of his sincerity, his past returns in a very tangible way and threatens to ruin his happiness.The plot is mostly excellent, beginning as a romantic comedy and turning into a serious drama. Khan acts his part well, first as playboy, then as reformed man. He is supported by a talented cast; Aditya Narayan was especially good.Twinkle Khanna was not particularly convincing as Komal, nor was the part written well, as Komal was not entirely likable. This detracted from an otherwise great movie.

I have watched this film many times, and will say this one thing that it is a light romantic complete family entertainer, Salman's acting is among the best of his career and all other cast is first-rate.The scenes between Salman and the kid are very sweet,cute and sometimes emotional,Anupam Kher as always is dependable and of course Johnny Lever is hilarious.Twinkle Khanna can be called as the surprise package here as she delivers unexpectedly quite a credible performance .The songs are hummable and can be heard repeatedly,they are beautifully shot too.The film has also got repeat value, all in all a sweet bollywood entertainer,the only problem could be that it drags a bit in the end reels,though still a must watch !

Deepak Sareen has indeed come up with a great fare.A musical with a good plot having it's moments of fun as well.The story is realistic and one that everyone can easily relate to.The subject has been treated well by the director. Story, screenplay (Honey Irani) stands out.The songs O jaana , 'Chal pyar karegi',' Pehli pehli baar','is dil mein kya hain' are good Johnny Lever's scenes are terrific.Makes you laugh,indeed. There are other good scene's that make you smile involving Salman,his son and Twinkle The story is really nice.It is indeed a must watch,and does have repeat(viewing) value. All the actors Salman,Anupam Kher,Twinkle,Lever,the child artist(Aditya) are first rate. It's a light hearted, but strong movie with good music and also good performances.

Perhaps, had I not been a social worker or recently seen much better films such as Hum Aapke Hain Koun, Hum Dil De Chuke Sanam, and Pardes, I might have enjoyed JPKHH better.I felt that there were several areas that did not ring true with either Salman Khan's character or the storyline and those areas were so blatant that they had a jarring effect. I especially did not like a scene where a child popped an adult's pill used to comic effect. Johnny Lever's pill popping was totally unnecessary to the entire film and dragged it to a lower level.I would still have to give this film a 7/10 because the acting was very good, the story was OK and had a few logical surprises, and the sets, scenery and songs were all fine. I just feel that, with a little fine tuning, JPKHH could have been a much better film.
