It has been done by non-Swedes from all appearances but whoever did it had done his/her homework, as many of the points are those which are easily glossed over by others who speak of the place.
Louie Verrechio gave a very good talk on Our Lady of Guadalupe which, although I shall not call a must-watch, certainly is at the very least a should-watch. There is a movie about Our Lady of Guadalue, "The Blood and the Rose", which he cannot recommend highly enough. He thought he knew about the apparition, but after watching the movie he realised just how little he knew.
