This movie is so sensitive and realistically portrayed that I think it touches a chord in anyone who lives abroad or has family abroad. SRK as the NRI working in NASA missing something in his life although he has all the material comforts has given one of the best performances of his career. Gayatri Joshi as the girl who doesn't want her nanny to leave her to go live with SRK in the US, is also very natural and believable. The old nanny torn between her love for SRK and Gayatri has given a heart warming performance. The Ek tara and Rahi chala chal songs are very catchy and hummable. I highly recommend watching this movie.
