"Kyun! Ho Gaya Na..." is a very low rated film on IMDb--with a current overall rating of 4.4. I would never rate the film this low, but can understand some folks' displeasure with the movie. It feels like a couple different films pieced together and the chemistry between the two leads is sometime lacking.
As for the first portion of the film, it's very much what you'd expect from an Aishwarya Rai Bachchan movie--full of romance and a formula I've come to expect from her films. This formula involves a desire to choose one's mate, meeting and hating a man, falling for the man, some even that tears them apart and, ultimately, the pair meeting again and marrying. I've seen it so many times that the first half felt like a case of deja-vu.
The second portion is pretty strange--with a completely different pace and setting. In this second half, Amitabh Bachchan (later for become Rai's father-in-law) is such a dominating presence that if feels more like his film. Only at the very end does the big climax come and the man (Vivek Oberoi) comes to his senses and runs to his lady love. The end. The final result is long and meandering feels much more like a hodge-podge than a coherent movie. Because of this, the film is not among my favorites in the career of Aishwarya Rai Bachchan. It also has a few bad moments--such as the ridiculous fireworks scene.
By the way, if you know who the chef Todd English is, look at the character Ishaan. He sure looks like an Indian version of this celebrity chef!
