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.
If we want to see on this a Earth a true shepherd and not a hireling - unlike the main man in Rome and his gang - then we could hardly do better than look towards Bishop Giovanni Martinelli, the bishop of Tripoli, who refuses to leave the city so long as there is a single Christian there.
