I think your first question is the most contentious. More than 90% of the show is speculative and added background to the Gospels. There are parts that show the biblical story but they are a small portion. That said the background is in support of the biblical story. The show seamlessly interconnects to the Gospels account. It isn’t a perfect show but it is well done and I would recommend it. It packs an emotional wallop that is hard to ignore. As an example of the background. We know from the Gospels that Peter was a married man but we know almost nothing about his wife from them. The Chosen makes his wife a significant character. If that isn’t your cup of tea then it isn’t for you.
Well said.
As a follow up the show makes you want to delve deeper into the Bible in a way if you are curious about what is presented and where in the Bible are the references.
