The main plot and theme of the movie is that lovers think they are perfect and life after the marriage will remain beautiful but marriage brings out totally a different character of both boy and girl. Life is not the same after marriage. There is a dialogue at the end of the movie which pretty much conveys the story theme - Kal main premi tha, aaj ek pati hoon(I was a lover yesterday but today I am a husband).
It's the story of Amar(Rajesh Khanna) and Mansi(Sharmila Tagore) who are in love and are married but life after the marriage is not bed of roses for them.
Basu Bhattacharya has done a remarkable job by bringing out such complex topic and dealing with it so beautifully. He calmly narrates you the story of Amar and Mansi. Their love, their fight and their drifting apart, all of them are shown beautifully.
There are some interesting dialogues throughout the movie which actually touches your heart. Like there is a dialouge which Mansi says, Why does people hate love so much(Log pyar se kyun itni nafrat karte hain)? It makes you think and the characters forces you to think about their issue and relationship.
Some scenes actually leaves a lot of impact. It's Rajesh Khanna's sheer genius which reflects in the movie. Most probably his one of the best performances . The way he delivers dialogue with full conviction is superb. His characters has two layers, one is calm and composed and never afraid of doing the right thing. Another layer of his character is when the couple start drifting apart. And both of the layers are shown beautifully. It's actually a Rajesh Khanna's movie.
Sharmila Tagore is simply brilliant. She is always so expressive, even with her eyes.
You feel you are there with both of them, the story greatly connects with the audience.
