It seems like you're suggesting that many contemporary film scores lack a crucial element that contributes to their overall impact. One commonly cited missing element is melody. In many modern scores, especially in certain genres, the emphasis may be placed on atmosphere, texture, and electronic sounds rather than strong, memorable melodic lines.
Melody often serves as a way to connect emotionally with the audience, and when it's absent or underdeveloped, the score may feel less engaging or memorable. Other possible missing elements could include harmonic complexity, thematic development, or emotional depth.
