Transferring Elena Ferrante's books onto the screen is not an easy endeavour; they are not plot driven stories, actually the plot is at times so thin to be barely perceivable. There's a lot of soul searching, introspection, her prose is harsh as sandpaper, her characters are flawed, tormented (and sometimes tormenting) people. All these - and many more - fine ingredients conjure up pretty unique and atmospheric ambiences. And, as I said, transferring this complex bundle of intangible elements into a movie is hard.
The operation has worked wonderfully once already (with The Lost Daughter, with a superb Olivia Colman) and it is working partially in The Lying Life Of The Adults. The are several remarkable things in this production: the acting is pretty good across the board and it succeeds in bring to life a gallery of strong characters. The portrayal of Naples is very realistic, never falling into clichés of caricatures. And finally, the underlying feeling of uneasiness which pervades the story is rendered very well.
On the less positive side, a good editing would have cut down significantly this production to 4 episodes max. Lastly, I thought the presence of the soundtrack was rather intrusive, it was one song after the other, and I found it detracted from the pensiveness of some situations.
