haha, i didn't mean to school anyone...just sayin', i've made some of those mistakes too but i learned that skimming the previous page at least catches you up on the latest news and topic of discussion.
as for using the old theme, i love it to death and it's undeniably Superman...but i also feel that it's time to move on and let Superman evolve. Indiana Jones and Star Wars are bad examples if you ask me because not only were the more modern movies inferior to the earlier ones, but also because Indiana Jones and Star Wars were first concieved as movies...not novels, comics or any other literature.
a more appropriate comparison would be James Bond, since he was first a character from a novel turned movie that uses the same theme despite multiple actors. however, i'd argue that James Bond's theme is a lot more action friendly and versatile. it's a theme that you can use whether he's running after a bad guy or sipping on his vodka martini. William's Superman theme, while being iconic, is more romantic and doesn't lend itself well to actions scenes especially modern ones. Bond's theme can be changed to match the pace of the action and it never sounds weird, but if you play Superman's theme too quickly it sounds forced and it STILL sounds too slow for an action sequence.
so while i respect and admire William's score to this day, considering this is supposed to be a clean slate they might as well go with an entirely new theme/score. of course, it should still feel like a Superman theme but it also should be as versatile as James Bond's theme. i honestly don't think that a new theme can be as iconic as William's theme is, but if it feels like Superman and can be used whether Superman is just floating above the city or punching through multiple enemy robots then it would be just as great!
