Mann is in my honest opinion one of the best films of 1999. It is at first a very nice, light romance which later turns into a sad and emotional drama. The story is very beautiful and is reminiscent of the 1965 classic 'Arzoo', the music is fantastic, and the acting is very effective. Among the songs, "Khushiyan Aur Gham" is one of my most favourite songs ever. Aamir Khan delivers an excellent performance. Although he is not very convincing as a womaniser, he is very good as a suffering lover. I think the best thing about his acting at that point of time was his simplicity and restraint, and that he never tried to do more than required (as I said, at least until that point of time). Manisha Koirala gives an amazing performance. She is intense, compelling and moving as always and does not at any point try to victimise her character. The film's big tragic twist is a tough moment to see, a moment which makes you realise how unexpected life can be and how important it is to cherish every moment of it. This is a wonderful and touching picture. I highly recommend.
