Raj (Hrithik Roshan), Tina (Kareena Kapoor) and Pooja (Rani Mukerji) are childhood friends. When they are still kids, Raj's family moves to London. Raj keeps in touch with his childhood love, Tina, via e-mail, but Tina lets Pooja do all the replying. Consequently, while Raj thinks he is exchanging mails with Tina, he is actually doing so with Pooja. Resultantly, Raj falls in love with Tina although the latter is hardly aware of his likes and dislikes, leave alone loving him. Here, Pooja falls in love with Raj. The falling in love happens only because of the e-mails.

Now grown up to be a handsome man, Raj comes to India for two weeks and is besotted by Tina. Pooja does not express her hidden love to him, choosing, instead, to sacrifice it for the sake of Tina. Before Raj returns to London, he expresses his keenness to marry Tina who also has now fallen in love with him. After a few days, Pooja reaches London in search of a job and her interaction with Raj there makes him realise the truth - that it was Pooja with whom he had been exchanging mails all these years. Armed with this truth and noble-hearted Pooja's reluctant admission of it, Raj tells her of his mistake in falling in love with Tina. He now promises to get married to Pooja and also makes her agrre to his proposal.

Back in India to break the news, they are faced with the death of Tina's father who had been her only living family member. Pooja yet again decides to sacrifice her love. Tina, oblivious of what has transpired in London, is happy to have Raj back. And Raj is confused - he wants Pooja but humanity demands that he not break Tina's heart at this juncture. Soon, Raj's parents, also unaware of the love brewing between their son and Pooja, fix a date for the marriage of Raj and Tina. But Raj tries to woo Pooja again. Ultimately, Raj agrees to marry Tina, as desired by Pooja, but he has a pre-condition. He tells Pooja that he would not get married till Pooja too did not get married to any other man. Even while the sacrificing Pooja accepts the marriage proposal of Rohan (Uday Chopra), if only to ensure that Raj and Tina get married, Raj again tries to dissuade Pooja and pleads with her to marry him. An emotional climax is where the problem is resolved.

The one-line story of two friends loving the same boy is given a new twist by introducing the concept of the relationship and love developing through e-mails. But a major flaw in introducing the novel angle to an age-old story is that Raj is not shown to have fallen in love with the writings of Pooja (who he thinks is Tina). In the absence of his love for her thoughts, philosophies, ideologies etc., there's no reason for Raj to say that he's actually in love with Pooja and not Tina.What, perhaps, the writer-director wanted to convey was that Raj lays down the condition, supremely convinced that Pooja would not be able to fulfil it and so he starts getting frustrated when she gets ready to fulfil the condition. But this does not get conveyed to the audience with the result that Raj, who is the hero, starts looking like a spineless creature, a negative character when he almost forces Pooja to not fulfil the condition.

Hrithik Roshan overacts most of the times. He looks terrific, no doubt, and also dances extremely well but in the acting department, he fails to win the audience over. Rani Mukerji is sincere and delivers a fairly good performance. But why is she so heavily made-up? Kareena Kapoor also overacts, continuing her K3G character all through. Debutant writer-director Kunal Kohli's sense of drama is poor, to say the least. As a story-screenplay writer, he fails to create any impact, going wrong even in characterisations. His dialogues are ordinary for most of the film. Kunal's direction is average, at best. Debutant Rahul Sharma's music may be melodious but a love triangle of this kind needed only hit music.Foreign locations are eye-filling. Production values are rich. Sharmishta Roy's sets are beginning to get stereotyped. Technically, good.

On the whole, Mujhse Dosti Karoge! will have few friends talking good about it but the majority will be disillusioned by the poor and flawed script. For its distributors, this will be one friendship worth forgetting. A heavy loser!
