It isn't the epistolary novel put to digital media - that wouldn't be possible would it, as it would still require a screenwriter/adaption - so complaints that it isn't that are a bit weird - also part of the joy of the epistolary form is that the authors aren't an objective narrator so as you read you fill in the gaps, guess at the truth, compare and contrast. That is what this take does, it is an expanded universe imagined from those letters and using more modern critiques of the excesses and hypocrisy of the historical period. Its fun, fruity and with enough faithfulness to the time (with the added glamour and gorgeousness and grime and stench in other settings, that you want from entertainment) to give new insights and considerations into this time in France. The acting is largely good, the script and dialogue trot along nicely and are funny and intriguing without being too earnest or 'olde worlde' clunky, and the cast, costumes and sets are presented brilliantly, producing a well realised world. Ongoing and boring complaints from reviewers who are obsessed with how much melanin some actors have proves again that they need to read more books (I mean Jean-Baptiste Belley was elected to the French Parliament 10yrs after the first book so the idea that people of colour weren't in respected/high positions at this time is pure nonsense)
Worth a watch.
