Black is a dramatic movie in every frame. The way it is composed, shot, acted and scored - it is as if the entire movie is climactic. I was quite impressed by it when I first saw it, but regrettably, the movie hasn't aged that well in my mind. I still think it's a beautiful movie with two extremely good performances, but it falls a mite short of being a great one. Who knows, maybe my opinion will change again with time.
There is, however, one scene that I consider great. It comes right at the end of the first half, when Debraj Sahai (Amitabh) has just managed to break through to young Michelle McNally (Ayesha Kapoor), teaching her how to say "water" in sign language. This entire first half has been about irresistible forces and immovable objects (you can pick who is which), with neither party refusing to give. At the end of that scene, when Michelle goes away, Debraj sits there, begins to compose a letter to his friend Mrs. Nair about his breakthrough, and halfway through that sentence, just breaks down and cries.
