The TLM and "a reverent liturgy celebrated according to the mind of the church" aren't synonymous in my mind. (You can have the second without the first, and sometimes even the first without the second.)
What isn't going to bring people or hold on to them is a faith dumbed-down to the 8th grade level, both liturgically and doctrinally. And that's what we've got in most parishes today. (Not mine, thanks be to God)
The issue is the same in most places. People don’t know what of why they believe.
