good family drama with lots of entertainment

I absolutely adore this movie. I borrowed it from an Indian friend and first of all fell IN LOVE with Hrithrik Roshan. Not even the bootleg tape I had could hide his beauty. I think I watched the movie 3 times in one week! Seeing as how the film is 3 1/2 hours long, that's saying a lot.
As always, Sharukh Khan is a pleasant diversion on screen. Kajol's character was a lot of fun too. It's nice to see a girl with spunk get her man! Nearly all of the songs and choreography were stellar. I will most definitely buy this one.
Like some of the other reviewers mentioned, there is definitely some over-acting but those few moments of suffering are rewarded with a variety of eye-candy. This film is definitely worth watching.

Karan Johar's Kabhi Khushi Kabhie Gham is one of the most ravishing, grandiose and melodramatic Hindi films ever made.
It is incredibly unrestrained and stormy in its emotional quotient, and yet so watchable, enjoyable and at times even pleasurable, that you can't but applaud to this spectacular show. It is one of the few films where overacting seems superb acting and overly melodramatic proceedings, despite being very cheesy and occasionally clichéd, become quite bearable. It combines realism and surrealism, comedy and heavy melodrama in a very unique style, which makes for an altogether colourful picture which is fun to watch.
The film is about relationships in family, about loving your parents and your family, about pride, values and regret. The well defined and written characters are used to create and present all these qualities. Even the least emotional scenes are accompanied by orchestrated violins, heavy piano and strikingly sad pictures on-screen. The film shows both the bright and dark sides of happy families, and while it never breaks new ground, never looks totally authentic, it is always entertaining in spite of its flaws. It depicts both the Indian traditional world and the western modern world and tries to bring them together in many instances.
Some of the film's too emotional scenes could have been better edited and partly cut. The cinematography is good, the sets are extremely lavish, and the narrative is effectively laden with numerous songs and many memorable moments of comedy and drama. The comedy provides great relief and lightens the otherwise more-than-enough drama, and the music is extraordinary. My favourite song is "Suraj Hua Maddham", a greatly melodious number wonderfully performed by Sonu Nigam and Alka Yagnik and extremely beautifully shot across some breathtaking locations. Needless to say, the chemistry between the two leads, Shahrukh Khan and Kajol, is as electrifying as ever.
Where acting goes, Amitabh Bachchan is restrained and displays well the hidden pain and the visible pride. Jaya Bachchan is superb as the subservient yet strong woman. Towards the end there is one very powerful scene in which she really stands out (you'll know which one). Shahrukh Khan in a typical, cynical and likable character, is great as always. Kajol utterly steals the show and proves her prowess as a gifted comedienne. She is hilarious in her comic scenes and equally shines in moments of drama. Her strong, charismatic presence is perhaps the best thing about this film. Farida Jalal provides excellent support. Hrithik and Kareena are unimpressive and inconsistent. Hrithik is over-expressive and far more emotional than required, and Kareena, while attractive and quite funny at times, badly overacts.
All in all, Kabhi Khushi Kabhie Gham has bits of everything: drama, melodrama, romance and comedy, all presented wholeheartedly in true Hindi-film style with lots of tears and lots of fun. It is an example of Bollywood entertainment at its grandest, and works as such. This is a movie to be seen with one's family. Go for it.
