Saathiya (2002) the remake of Alaipayuthey (2000) is definitely a fantastic movie on love and relationship. Though it may not be a path breaking film like Dilwale Dulhaniya Le Jayenge or Bobby, Saathiya does not have the trappings of 'filmi' romances. It looks so much real, contemporary and believable. Apart from romance, it also deals with tensions of coping and adjusting with married life. The performances of Rani Mukhejee and Viveik Oberoi also lend a lot of credibilty to the movie.

Am surprised at the answers here.boy mets girl,sing a song,and face resistance and then marry.this is not the epitome of romance.The most romantic movie as per me was Silsala.The passion between the lead characters was sobeautifully portrayed.and a very close second Sangam(RK).another super movie...and also the Devdas of Dilip Kumar!
