Didn't find anything "cocky" or "arrogant" about what Elfman said. If he believes his Batman theme is the only Batman theme that's his opinion. At least he complimented Zimmer's contributions from TDKT trilogy. That was the opposite of what Zimmer did while promoting TDK when he made a snarky remark about Elfman's theme being "jolly". Also Elfman's Batman theme is an actual theme compared to TDKT, which consisted of motifs, and BvS, which was mostly repetitive rhythmic pounding of notes. Can't blame Elfman for ignoring what Hans and Junkie came up with for Batfleck, which left a lot to be desired. It's easily my least favorite of the Batman themes I've heard, which is saying something with how much I've criticized TDKT scores. It wouldn't bother me if Elfman also ditched the MOS and Wonder Woman themes/motifs since I don't care too much for those either.
