aparajito (1956)
The second film in Ray's Apu Trilogy somehow trumps the first by packing more punch. While less universally aware, Aparajito makes the transition into the personal universe. Youth's self-interest that, at the time seems a charitable effort of "If I do not better myself, how will I benefit anyone else?", and in the end results in the realization that, just as the sins of one's father, life was happening while you were away and you paid no notice. As sequels go, Aparajito seems an inseparable companion to Pather Panchali, building on the earlier films' themes while simultaneously moving in a new direction.
