Perhaps you shouldn't try.
Coppola chooses to tell the story (insofar as it is a story and not just a succession of gorgeous tableaux) as the tragedy of the king and queen- victims of a system they were too feeble to change. Well, yes, that's one way to doing it- but it isn't very interesting. Shoes are purchased, cakes are eaten, baby sheep are fondled. The people of France- whose story is rather more compelling- remain off-screen until the very end.
Someone- anonymous- broke into the royal apartments and smashed a chandelier. Oh the humanity!
