Each and every one of the 6 Star Wars films by George Lucas have memorable pieces of music by John Williams. But The Force Awakens has none.
Even the fanboys who didn't like the prequel trilogy can't deny Duel of the Fates, Across the Stars, and Battle of the Heroes are instantly recognizable, and rightly earned their place in the pantheon of Star Wars music.
What does The Force Awakens have to offer? Only Rey's theme, which is tedious at best.
Rey's theme is something that sounds like a mix of the march of the Ewoks and Anakin's theme from The Phantom Menace.
Aside from that there isn't much in the score of the movie that's truly memorable.
Just like the rest of the movie.
"That's not true! Han Solo killed by his son is memorable!" some will say. Meh. That looked so prefabricated it was immediately obvious it was done as way to pander to the fanboys.
And the music? Well, I don't know if John Williams did it on purpose as a way to say "no, I do not agree with your bashing of George Lucas", but if he did, I now admire him even more.
