There's nothing wrong with the site, and I agree that the indentured servant phenomenon that moved so many millions around the globe deserves some sort of World Heritage recognition.  There's just so little to see at this site. Just one restored building, really, and a few other foundations/walls.  The small rooms do have signage that do a good job of explaining the whole "movement of indentured servants as a solution for getting cheap labor" idea once nations had banned slavery, and it was interesting to learn the history. Unfortunately, the downstairs museum exhibit hall was closed during the hours we visited (even though there were staff at the front desks, as they allowed me in to use the toilet), so we missed seeing that.
