Superman's theme was barely used. It was there but there wasn't enough 'super' in it. Just the slow parts and not the triumph parts if you know what I mean. Lex Luthor's theme was original and appropriate. Batman's theme was weak.
While the Wonder Woman theme is great, question...as it is used for most of the Trinity battle...is it really just the Justice League's theme? I mean it was used repeatedly in the final battle. Flaw.
Otis's theme from Superman: The Movie was later stolen which became Lex Luthor's theme.
I'm worried they are just going to substitute Wonder Woman's theme for the Justice League movie.
WW emerges in the Doomsday battle, that theme is heard, then, cut to her slowly rising her head from her shield...it is heard again...I think it's fine but then...it's heard for the third time once again after Batman says, "I thought she was with you"-trinity shot...and through-out most of the entire fight, only Wonder Woman's theme is used.
