The most annoying part of the movie .. poor story.. poor poor acting by Aish and Vivek... I never liked Viveks acting after Company ... His acting is completely mediocre... and lots and lots of stpidity .. even Big B's appearance could not lift this up... a complete waste of time !!! I don't know why Aishwarya is spoiling her career doing movies like these ... and that jackass Vivek will never learn how to act unless he gets rid of his stupid jackass attitude... This movie lacks everything from a good storyline to proper screenplay ... God knows when will Indian directors learn to put in everything in the right place I would not recommend this crap to anyone... except if you want to waste your time and blame the movie in the end

I was looking forward to seeing this movie when it first came out. I'm so glad i never watched it in Cinemas, i hate sleeping in cinemas. Vivek Oberoi was having a great career, with Great movies like Company, Saathiya, Road and Dum. His next film was a flop Kisna, but after that Kyun Ho gaya na marks the end of his good career. Starring opposite the very beautiful Aishwarya Rai, who he was dating. This is one hell of a boring film, with a lousy script. The twist of this film was utterly ridiculous. I cant understand why Amitabh bothered appearing in this lame movie. This film and Home delivery are Viveks worst movies of his good predicting career. Vivek delivers a unsatisfying performance and Aishwarya is only good for looking at. Aishwarya is no doubt one of the most overrated actresses in Bollywood. If you look carefully she never made any good films. Any actress that stars opposite Shah Rukh Khan have no worries, and don't tell me Devdas and Hum dil de chuke sanam were good films. This film bored all the way, don't waste your time.

This (Kyun? Ho Gaya Na)has got to be one of the BEST Bollywood Romantic Comedies ever! The story line is great and it's great to see Aishwarya in a modern role and she look Hot as usual. The acting by all was great and NOT over done. The perfect amount of comedy, romance, emotions and backdrops. The appearances by A. Bachchan and Suniel Shetty is great!!! Music is good too. Aish and Vivek seem to work well together with the perfect type and amount of chemistry needed for this movie. The ending has a great little twist that just makes the movie soar expectations. Ignore what the critics have said against it and judge it for yourself. I definitely recommended for any day of the week!

The much hyped Kyun Ho Gaya Na, surely disappoints. Then main flaw in this film is the dull storyline. There are a few touching moments in this film, but there aren't strong enough to stay with you even after the film has ended. Kyun Ho Gaya Na, lacks emotional content. And even, the comedy is not really funny. For any love story its important that the on screen chemistry between the hero and the heroine is just right. Sadly, there is absolutely no romantic chemistry between the real life lovers Ash and Vivek. Music is quite good, especially Pyaar mein, No no and Aao na which have been picturized well. The remaining songs could have easily been cut out. Cinematography top notch, the film looks gorgeous. Aishwarya Rai doesn't look the part of Dia and her performance is disappointing. Vivek O'beroi is excellent. He not only looks, but also plays the part of Arjun effortlessly. Vivek's performance comes out as natural and breezy. Om Puri is good as always, Rati Agnihotri seem to getting a lot of mother role lately and she plays them extremely well. Tinu Anand is fine in a small role, Amitabh Bachchan is annoying. Sorry to say that but, an actor of his caliber shouldn't play such mediocre characters. His performance looks fake and childish. Sunil Shetty is adequate. Unfortunately, Kyun Ho Gaya Na doesn't live up to expectations. Apart from Vivek's acting, a few good songs and the fantastic visuals nothing else is appealing about this film. 6/10.
