Nostalgia? How about a sense of the sacred.
The comments of this young man (not much younger than myself

) answer your concerns beautifully:

I can’t speak for everyone, but here’s my opinion as an under-30 Catholic: There’s a shift going on and more and more Catholics want to return to standing out from the general culture. I hope this isn’t a full repeal of Vatican II, but rather a correct implementation of it where we engage and change the world around us without becoming part of it. I think this may be the real story; the liturgy is just the field where this battle is played out.
I’m noticing more and more that I desire the Church to not only be a spiritual refuge for sinners through the sacraments but to also be a physical refuge. Where my friends and family tell me to ignore the hard teachings of the Church, I wish my fellow parishioners would push me to try to live them to their fullest. Where mass media and culture tries to force relativistic values on everyone, I wish there was a strong Catholic culture to help create a buffer and affirm absolute truth. Where art has turned into a medium of conveying an artist’s personal agenda rather than the truths of the human condition, I wish my church were filled with stained glass windows and statues and hymns to flood my senses with inspiration.
This is how it should be, but all too often it’s not. And more than the examples above, the liturgy should be a refuge from the world around us. It should take us both to the foot of the cross and to the great wedding feast when Christ comes for his Bride. Because Mass is the most important thing in a Catholic’s life, I think the liturgy is where this difference between what the average parish should be and what it really is becomes the most evident.
While I support the liberal use of the Traditional Latin Mass, I don’t think it’s the only option. What people, especially those too young to ever have attended a TLM before the new missal, want more than anything is reverence - a Mass that lifts them up to God. Because the Novus Ordo Mass is so frequently abused, or at the very least not celebrated as reverently as it easily could be, young people turn to the TLM. If they could find a reverent NO Mass near them with incense and altar bells and high quality hymns and meaty homilies and the priest facing East and Latin for common prayers if not the entire Mass, I think most orthodox Catholics would be happy. These things are the standard for the NO Mass, yet sadly they’re hard to find so people opt for the TLM if there’s one available.
