Praying with the liturgy
The problem with liturgy in the vernacular: people no longer study the parts of the Mass. The do not come to Mass equipped with a missal to help them follow what is going on. The missal has been reduced to the missalette, which provides no resources for private prayer and meditation during the Mass.
It's now a spectator sport. "Entertain me. Your job is to move me."
This is why the new liturgies are structured as rock concerts are. Music, staging, sound, lighting, and special effects.
