It's no secret that I love Downton Abbey, and my visit to Highclere Castle is one of my favorite days ever. Each year, I watch the first few episodes as we get them aired to us on PBS, but as soon as the DVD comes out, I buy it and binge watch the remainder as soon as possible.
It's a magical place, and they bring that to the viewer in a way I've not noticed before. I also thought that they did a similar job of showcasing the inside. There are sweeping views of the staircase, there are up close shots of details in the great hall, they let the camera linger on the library, etc.
Episode 6, as you probably saw in the previews at the end of Sunday night's episode, involves the family opening Downton up for tours for a day. It is a super funny episode. You will love it. This also gave them a great opportunity to really show the viewer the house in greater detail than before.
So again, without any spoilers, I will say that I found the ending to be quite satisfying, and I can't wait for everyone to watch so that I can discuss it with someone other than Lola dog!
