Apparently so. The war ended in '45. Vatican II closed in '65. In the twenty years between, the Catholic Church was at its zenith with vocations and schools and hospitals and missions and church attendance and baptisms and conversions and the faith itself at an all time high. Bishop Fulton Sheen was more popular on tv than Milton Berle. On the Waterfront and Sound of Music were huge hits. Within ten years of the close of the Council, the Church had precipitously imploded. Now it's the subject of Hollywood jeers.

These effects must be due in part to something else.
Protestants are also the subject of jeers.
(Side note: you may very occasionally get a sympathetic Catholic priest role. You will never see a Protestant minister portraied as anything but a lunitic or murderer.)
The visible Church would not have crumbled so swiftly unless the rot had been already well advanced. It's the very definition of a healthy Church to have been able to absorb assaults like this. That this never happened ought to tell you something.
