Query: Zefirelli's film adaptation is excellent.

Zefirelli draws our attention to the fact that the musical material at the beginning of the opera recurs at a later moment in the film by suggesting that Violetta is recalling the entire story. This approach is consistent with a musicological examination of the score and demonstrates marvelous insight by the director into the music. Zefirelli's great musical sense pervades the entire film.
