The final "world-uniting" tune was just awful!
I hate it when movies build up to an "amazing" song like this, only to have the actual tune be so utterly forgettable.
The concept of mixing Mozart with Hendrix and Louis Armstrong could have been a lot of fun, and I was really hoping they would turn it into some kind of mixed genre medley where each instrument got a chance to shine while building each other up, akin to Mike Oldfield or Shpongle or something in that vein...
But instead we got a super-lame drum beat with really lousy bass, and guitars that all seemed to battle against each other for attention. There weren't two notes in there that were even remotely catchy in any way.
At least the second film ended with a somewhat decent rock song that, albeit a bit cheesy, you could kinda suspend your disbelief and pretend that it was supposed to be sorta impactful....
But the garbage they threw together in the third film was just simple uninspired riffs that made it obvious the filmmakers weren't even trying. Anyone could make much catchier stuff in mere minutes by just playing around with the standard demo-samples on any android/iphone music app.
