It's been a while since I've seen the cinematic version of Hemingway's classic short story about a couple who struggle to decide to do with an unexpected pregnancy, but here is what I recall.
The musical score added both a tension and a sweetness at crucial moments, underscoring in an audible way the tangled emotions of the man and the woman.
Visually, the cinematography is beautiful. Unlike some films that take liberties with interpretations of locales, this filmmaker uses the actual mountains and vistas of Spain. The train, so symbolic of the passage the two must cross, the darkness and light they encounter, both emotionally and literally, is brought to life, putting the viewer/reader in the characters frames of mind even more vividly.
Furthermore, we see their dilemma much more clearly. The hotels, the luxury, the freedom the couple will be forced to give up should the woman decide not to have the abortion.
