I listened to this last night. It's the most I've enjoyed a surround mix in a long time. Beck's Sea Change and Flaming Lips' Yoshimi got me into surround mixes back in the early 2000s, but I hadn't really loved anything since (despite listening to dozens of surround mixes including Atmos with height speakers).
I like Pink Floyd, but just casually. So, I don't know the original mix of Animals that well. I'm sure some purists might have issues with the newer one.
Regardless, I really like this. I prefer active mixes with plenty going on in the rears, etc., but most of them seem to be "too much" for me. I appreciate how Animals is mostly focused up front, with one or two elements popping out into the 3rd dimension. Instead of constantly being surrounded by a barrage of instruments from all directions, things just momentarily go behind (for the most part - there were also effective sections with instruments all around). To me, the instruments sound more clearly separated than Fragile, Pawn Hearts, or even the newer Tom Petty and Grateful Dead Atmos mixes. With Animals (and Sea Change and Yoshimi), it's like I knew what to focus on as opposed to feeling overwhelmed and unsure. I look forward to repeated listenings to further understand why I prefer this over so many others.
