At least the film HAD a recurring theme. I think what made filmscorring so great in the '70 and '80's where the immediatley recognizable themes for films like this. Okay, so Michaels theme may not be as ingenious, but it IS a recurring theme and I think it works very, very well..! I think for instance that the new Spiderman films could have really, really used a very memorable theme, but honestly: can anyone hum the Spiderman theme?
No.
I can remember Harry Potter's theme, the Shire theme from LOTR, the classic themes from Star Wars IV-VI and some of the themes from AOTC.
Themes work.
