This is my favorite Nick Cave record, and as such it's also my favorite of his 5.1 releases. The album came as he was cleaning up from a long heroin addiction, and the songs are less bleak and aggressive, more subtle than anything that had come before -- but no less menacing. This kicked off a string of great records that he and what is regarded as the classic lineup of The Bad Seeds released over the next decade.
Anyway, as 5.1 mixes go, none of the releases are swirling 360-degree tours de force of the prog-rock variety. Rather, the music is given space to breathe, spread out nicely across the sound field. Having spent more than 20 years with the original stereo mix, to my ears the surround mixes do as intended, providing a new listening experience, filling the room and enveloping the listener in sound, with various elements neatly placed here and there, as noted by the reviewer above.
If you are new to Nick Cave and the Bad Seeds, this is the place to start.
