In Las Vegas, Rahul Kapoor (Imran Khan) , an unemployed architect, meets Riana Braganza (Kareena Kapoor), an out of work hair stylist, first at a superstore, then at a shrink's clinic and for the third time at a noisy bar on Christmas eve. He, 25, weighed down by his parents' expectations, leads a straitjacketed life. She's 27, carefree, roams Vegas on a scooter and loves to live life one moment at a time. Their nationality is perhaps the only common thread that binds them.
And then on Christmas eve, in a drunken stupor, they enter a chapel as witnesses and come out a married couple. Khan's voiceover tells us that it's very easy to solemnize marriages in Vegas, that two people can get married at any time, place and in any condition (in their case, inebriated).
Their marital life begins with the decision to annul their marriage. The rest of the movie follows the couple from Las Vegas to Mumbai and back, and how they go about ending their marriage.
Funny dialogues and able performances by the lead couple and supporting cast make Shakun Batra's directorial debut very watchable.
Riana's family is adorable, specially her father. Rahul's parents, played by Ratna Pathak Shah and Boman Irani, are perfect as the upmarket SoBo couple. Amit Trivedi's music is noteworthy with 'Auntyji' being the most catchy song. The washroom encounter involving Rahul and his date (Soniya Mehra) is easily one of the funniest scenes of the movie.
Kapoor makes it a point to brighten the screen each time she appears, reminding you of Geet from Jab We Met. Khan, as the no-nonsense boy who alternates between being a 'tight-ass' and an uninhibited person is very likable.
Just the way Riana tells Rahul that he's perfectly average, I'd like to tell you that this movie is perfectly above average.
