I watched it again. The opening montage with Superman memorial flags all over the world, had the beautiful
"Everybody" by Sigrid, very Zack Snyder feel. Then we get to the
bank heist and mofoing Elfman goes into this
junk of an intro, which apparently is a modified WW theme. Wtf is the first 20 seconds? Penguin revival track? Doesn't fit the mood at all, except trying make it "light hearted" somehow.
Aside from that, I noticed all the parts where Batman/Bruce wasn't brooding were all Whedon, based on what
ultracal31 said. The part about "Something's definitely bleeding," and the high-pitched Bruce voice when talking to the team (with the scene ending with another question about talking to fish.) The scene after that was with Wonder Woman in the bedroom, and Bruce's voice is back to the BvS brooding sound (Synder scene.) The airplane scene of him shaving and talking about Penguin days also didn't sound like BvS Bruce, because that's a Whedon reshoot. Sigh.
Right? In BvS, when Batwing flew towards the building and he jumps off, that score was hair raising. Instead we get Danny Elfman in JL. I never really like Batman Returns, and watching it recently, part of the reason was the over-the-top score. I hope we don't get a repeat of the 90s. Armors getting more and more complex, things get more and more over-the-top.
