The Pope is gonna be critiqued by many for not going far enough in his actions and I can see where people making these criticisms are coming from. However given the scale of the problem, the scale of the mess he has inherited, combined with the entrenched resistance to his reforms he is facing, on the whole I would say Francis is doing a good job trying his mightiest to address this. 

The fact that he wrote a preface to a book written by a sex abuse victim on this topic is pretty amazing. The fact that he has set up tribunals and is the first Pope to have prosecutions of abusers(such as the case involving priests from El Salvador) is also pretty historic given that every Pope before him going back to John XXIII failed to do so. 

So even though people may not like the pace of how this are going, the Pope in his own way is making changes slowly and incrementally that in the long run in the future, will seem substantial.
