I enjoyed the ending. In the hospital, Pietro realized that Enea was surrounded by people who truly loved him. Thus, he resisted his own desire for Enea in the final farewell scene to prevent something that might disrupt or complicate Enea’s life. The initial disappointment on Enea’s face, along with Pietro’s quick moment of regret after Enea left, was a nod to the audience’s desire for a more conventionally romantic ending. But ultimately, Pietro’s decision to let Enea go was an act of love.
So again, I enjoyed the ending.
I was a bit confused, however, by Titti’s role in the latter part of the film. I didn’t get why Enea would be haunted by her.
