I am delighted to find that Dr. Márcia Balisciano, the Director of the Benjamin Franklin House in London, has responded with a long and detailed comment to my rather snarky review. I recommend my readers take a look at her full and exciting description of changes made and yet to come, including a better arrangement for ticket sales, weekly opportunities to tour the house without the theatrical "historical experience," and much more.
As an early American historian, I really do want to see this museum succeed, and all these changes seem terribly promising: It's great to see museums taking a proactive approach. My only continuing beef is that I remain skeptical that architectural features alone can evoke imaginative response in most audiences, but I'll hold my fire for now, and cheerfully accept the invitation to make a repeat visit to the Benjamin Franklin House at the next opportunity, this time with a child or children in tow. For now, if you're considering a London trip, please do read over Dr. Balisciano's comment (appended to my original review), and consider booking tickets to visit the house. I will be interested in readers' responses in future.
