This 100%. I don't want Williams back for that very reason, I don't want him bringing back the 78' theme. Leave the dated camp out of these films please.If by "real magic", you mean the camp of Williams' Superman '78 theme, then I'm definitely not interested in that.
There's lot of camp elements in the '78 film...
But that theme is most certainly not one of them.
Nick Glennie Smith? The guy who composed The Man in the Iron Mask (1998) and Home Alone 3 (1997). I think he might be good for Justice League. His theme for The Four Musketeers was heroic and triumphing. Listen to the track "Surrounded" if you know what I mean, see it on film.
I wouldn't be surprised if Junkie did the score for JL.
I really hope they get Howard Shore for Wonder Woman. I think that'd be perfect.
Or Aquaman?
depends on what type of soundtrack you want if you want bombastic energy pounding score keep junkie xl
if you want adventurous sweeping epic you get someone like Michael Giacchino
Sounds good to me...I'm biased too but I think it'd be epic for the king of Atlantis to have the music scores as epic as Aragorn's and those middle earth rulers's.Eh, Wonder Woman. I may be a little biased towards LOTR, but that's the reason I want Howard Shore. I think it'd be cool if the Amazonians had a sort of Elvish-sounding theme. Maybe he could do both? But if he could only do one, I'd prefer that he do Wonder Woman.

Or Aquaman?
The Justice League needs a theme (and epic hero group shot moment) like the Avengers had. I've never been so happy in a theater before. The music played a large role in that.
The Avengers theme sounds cheesy as heck to me, not that it's a bad thing.
I'd personally want someone like Christopher Drake or Nick Arundel, since their pieces on All-Star Superman and Arkham Knight, respectively, are pretty much the quintessential modern themes for Superman and Batman, imo. That All-Star Superman theme, especially, is all types of feels. Although I'm not sure how their style would fit for a full length blockbuster though.
OMG yes. There. That. Him. McCreary is an amazingly talented composer. His work on "Battlestar" was incredible, he can do so many things so very well. Give me Bear!As for Justice League, I still wanna see Bear McCreary do it.
