Schultz,
My father, when he was a boy in 1945, used to serve regularly at the 7am Sunday Low Mass, which took less than 40 minutes, according to him and my four uncles, who also regularly assisted at the same Mass (the Beck boys had a monopoly on that particular Mass, apparently). The way things were done in 1945 is far different than the way things are done in traditionalist parishes today. Unless you are at least 55 years old, you really have no recollection of the "good old days" and anything you've experienced post-Ecclesia Dei is a romanticized version of pre-Vatican II.
Back in my SSPX days, this wasn't uncommon either (Low Mass said in 30-45 minutes, depending on the Priest.) So, while your observation about modern-day-traditionalist "romanticism" probably holds some water in some places, I don't think it's universal. And of course, anything is preferable to the
essentially Lutheran service which the Vatican cranked out after Vatican II for popular consumption (and that includes a "said at light speed whisper" low-Mass in Latin with only one server, no sermon, no choir, no nutthin'.) Now that I think about it, my experiences of the "novus ordo" low-mass weren't exactly elaborate affairs either...so I don't quite see just what the real big deal was, save for a descent into banality (if that's you're "thang".)
