I have to admit, the prologue in BvS, the "Beautiful Life" was very good. It was surreal and moving. I just wish Batman had had a better theme. Luthor's theme was solid and Wonder Woman's was phenomenal. Shame for Batman though. I think he deserved a better theme. It really didn't seem like a good idea at all to hire Zimmer and Junkie XL again to try and re-do Batman again, with the exception of Superman, Wonder Woman and Lex Luthor's themes being good, I think it might have been a good idea to have chosen an additional composer to work on Batman's theme.
Slightly off topic, but I know people love Christian Bale's Batman. For me, it'll always be Michael Keaton. I just don't think either of the other Batmans were as cool as Keaton's take. I would elaborate more on it, but maybe in the Batman discussion.
I think this was partly due to Danny Elfman's score. BvS didn't have a memorable Batman theme you could hum to yourself, but Elfman's Batman score is iconic. It was dark, cool and heroic. It had theme.
Every time I look at Bale's Batman, with Zimmer's music, I think it's good, but I still feel like I'm seeing a version of Batman, and not the definitive Batman. Affleck comes as a close second favorite Batman to me next to Keaton. When I see Keaton, I see Batman.
