There is no real "problem" with the Vatican II documents, but problems in the full understanding of them for those who fight what is new to them. You are now limiting the authority of the magisterium, and a Church council no less, in an attempt to preserve what YOU want.  Wow. You are increasingly angry and defensive, and that is clearly clouding your judgment, I see.  So, I would simply encourage you to do some reading now in the areas of liturgical reforms, Vatican II, and Church reform overall.  I can provide many references, but here I will mention just three. "True and False Reform in the Church" by Yves Congar, O.P., then "True Reform: Liturgy and Ecclesiology in Sacrosanctum Concilium" by Massimo Faggioli, and then "What Happened at Vatican II" by John W. O'Malley.  These are wonderful volumes with rich insights into the very topics under discussion here.  I hope you enjoy them as much as I did in my first readings.
