The Vatican reported that attendance at papal audiences at the Vatican in 2015 is more than half it was in 2014. There are many reasons for this not the least of which is the threat of terrorism in large crowds and the Vatican's notoriously lax scrutiny of those entering the St. Peter's Square for events.
I would suggest too, that Pope Francis is aloof in some gatherings and does not seem to generate the same excitement as the so-called introverted Pope Benedict who, compared to Pope St. John Paul II in his heyday was quite extroverted and generated immense excitement at public events be they Mass or some other type of audience.
Since Pope Francis, those at Mass are warned not to applaud the pope at the entrance and recessional and if you watch Pope Francis, he looks dour, almost mad, as he enters and leaves St. Peter's.
Compare this to a recession at St. Peter's for the Easter Vigil with Pope Benedict XVI who supposedly always ignored the pilgrims and never blessed them as he entered or departed the basilica:
And now Pope Francis:
Of course the traditionalists out there would prefer the somber, reverent approach of Pope Francis, no?
