In fairness, you could say that about any Star Wars movie (besides the original). The Force theme is the most memorable theme in cinematic history.
But TFA didn’t have an Imperial March or Duel of The Fates or Across The Stars to balance it out, which made it seem like the Force Theme was overused.
You got me on the Imperial March, no argument there, all time classic.
Across the Stars is undeniably a fantastic piece of music and one of Williams best, though I would agree Rey’s theme is in the same stratosphere.
Duel of the Fates is a fine cue, very catchy, but not very interesting as a recurring theme (shows up only at the end of TPM, a couple more times in AOTC and ROTS but with no variation or development).
Even if it seemed like it to you, the Force theme was certainly not overused in TFA. In fact, if I had to guess, of all the films in the saga TFA might be the one with the least amount of Force theme statements.
