I agree with this.  I suspect that Sr. Lucia was exaggerating the visions at the very least.  She kept having revelation after revelation from Mary after the fact, which is odd.  I also suspect that the Vatican doubts the authenticity of the entire vision or Lucia as a visionary, which is why there is no cause for her beatification.  However, I also suspect that Medjugorje is a fraud given that the visionaries have regular visits with Mary and have used their visions to make money.

The last legitimate Marian vision was probably at Lourdes.
