So after he concluded his lackluster scores for the Nolan batman trilogy he'll begin writing new lackluster scores for the MOS franchise. Oh goodie. So Hans is also a liar. He said a while back that he wouldn't score Superman "it'd be like trying top Beethoven's 9th" or something like that he said. So he must think he can top Williams' theme? Good luck on that.
They couldn't find anybody else? Somebody who could use a project like this. Somebody who's trying to breakout like Chris Bacon, for example. Or a established composer like Giachinno, Powell, Don Davis, Marco Beltrami, Shore, Desplat to name a few. Zimmer and his cronies are scoring every blockbuster movie these days it's pathetic. Hollywood give them a break already. This just proves that Zimmer is very overrated. He'll probably end up scoring the JL movie whenever that happens.
I'll try to give him the benefit of the doubt, but it's gonna be really tough for me. They really should've went with somebody else instead, imho.
