This movie came out last year and only released in the city I lived in for a month. 

I finally find the time and energy to see this movie yesterday as I know this movie is "heavy".

And it is very good. No graphic scene to shock the viewers. Just dialogue and good plot moving along as the journalists got closer to the truth.

The Catholic Church and its bishops and priests are wicked and powerful. 6% of Catholic priests raped children and the church knew about it for years. Instead of dealing with this the right way, the Catholic church used their money and power to suppress the truth denied justice for rape victims. 

That's the truth. Now the movie take the audience along for the journey of discovery. 

While watching the movie, this image of the Hulk, Batman and Wolverine half-brother Sabretooth team-up and fight against the evil Catholic Church. The surprising one is Sabretooth as the calm leader, while the Hulk run around being hotheaded.
