I listened to the first PIRATES score on Spotify a couple weeks ago and was shocked by how small and almost cheap it sounded in retrospect... And rumors aside as to who really wrote it, since Badelt is credited for the first PIRATES, you couldn't really put it on a list of Zimmer's best.
I haven't heard the first one in a while so I'd be curious to listen again and see how it sounds. I assume it's the samples and programming that are going to sound very synthy and Media Ventures-ish.
As far as the crediting goes, I think ALL of the PIRATES movie scores were co-composing setups? So in general that's a franchise that is hard to pin down credit for.
