The acting is superb all around, and the art & history lessons are fascinating whether you are familiar with the art history or not. And you don't need to be an expert because it's really about solving a mystery, contending with new clues, and watching further growth and developments between Captain Verlay and Florence. I have seen both actors in other shows and they are consistently real in every role, excellent actors. The sets are lovely, and every character is just right (tho I could live without Juliette). We just finished binging Season 4, I think it was the best ever, and will wait breathlessly for Season 5.
