I can see what it's trying to say but to me its messages are very mixed. The intended parallels with human xenophobia are made explicit on the BFI site.

A post-Brexit pagan dance fantasy about a troupe of Morris-dancing badgers trying to avoid the animal quarantine compound which has been built above their burrow. Living in a border town on the south east coast of England, the badgers are struggling to keep their old folk traditions alive in the face of change. They refuse to acknowledge the plight of their neighbours, the caged quarantine inmates, fearing physical and even ideological contamination, until Frank, a young badger, goes rogue.

Intoxicated by the exotic rhythms drummed out by the resourceful animals on their cage bars, Frank the young badger starts dancing forbidden new steps, risking the wrath of the Morris troupe. But when tragedy strikes, Frank must forge a new friendship inside the quarantine in order to help the Morris troupe survive.

The badgers perhaps briefly express some common 'animality' with the detainees - who may be all non-native species - it's not obvious. And I suspect there is a link with badger culling - humans could do with a bit of animality.

That the author uses morris dancers to represent the intolerant indigenous population is interesting but I think it's confusing. And it all ends without resolution; which may be deliberate - or not.
