"For one thing, Catholics old enough to remember the pre-Vatican II Mass know that it’s as capable of being celebrated in drab, uninspiring fashion as any other rite." - John Allen
Allen does say something I agree with - namely that those anxious for the old rite will be disappointed when they see that it can be celebrated irreverently and abusively. I suppose some might say that at least there won't be any "hippie music", though I would caution them not to underestimate the lengths to which liturgists will go to undermine all things traditional.
Not that I'm against this motu proprio business, not at all. I think it's immensely important, just not in the way you might think. My hope is that a wider availability of the traditional rite will cause both to influence each other over the next few decades so that the next missal will preserve what is best from each of them and will be an elegant and organic development of traditional Catholic worship.
Hopefully I'll be alive to see it.
