I was raised in the pre VII church and distinctly remember Masses that were less than 30 min., on Sunday, including Communion. When I got married we belonged to a parish that was a Priory of a certain Order, and there was a priest who was noted for his speedy Masses. We, along with my in-laws, deliberately chose to go to his Masses because he could get you “in and out” in less than 25 min. My husband says it ws more like 20 min., but I’ll give the priest the benefit of the extra 5 min.
My only complaint when the new Mass was introduced was that it was too long. I had moved to a new parish by then, and Mass was an hour long

I liked everything else, esp. when they switched to English. Now, of course, I could happily sit in church for a couple of hours (like at the Easter Vigil). But back then, it was a shock to my system, being used to much shorter Masses, and going, really, because I was obliged to, not really wanting to.
As for people being more educated in their faith pre-and post Vat. II, I think it depends on what you mean by educated. People certainly knew more of the Catechism and Church rules, but unless they were really, really interested, they knew very little else, and they often did not know the reasoning behind what they learned. It was not common to read or study the Bible, study Church documents, Church history, Apologetics, Theology, etc. Most of that was outside of the everyday experience of most of the laity. Today the laity is very blessed to have access to and encouragement to become well-educated in all aspects of the faith, although basic catechesis is sometimes lacking, but it is getting better. And now we are expected to do our part in evangelization and education and Christian formation–it’s not just the part of the clergy anymore. When I look at the multitude of educational opportunities taking place in my parish and those in my Diocese, and of the number of people involved, I sometimes am truly astounded at how far we have come in the past 50 years in this area.
I think that in the future there will be a trend back to more solid catechesis and a more faithful Catholicism. But I do not think things will ever be the way it was before Vat.II. But I think largely the time of experimentation is over, although there will be a few holdouts. I think we are finally learning from our mistakes.
