It wasn't so much a documentary expose but more of a slow, darkly humourous 'tour of duty' of things going wrong at the pace of treacle flowing downhill. You see the bad things slowly unfolding but everyone is either powerless or too disassociated to bother to intervene.
Disaster duly runs its course:

I did not know whether to laugh, but felt my heart slowly sobbing for most of the movie. Things ain't moved on since Alexander' The Greats time!
