Not everyone who attends the EF is opposed to the OF, or the translation (and by analogy, opposed to the vernacular). And I doubt that one could find a priest who says the EF who is liturgically casual or rushed, let alone sloppy. Some of those of us who grew up before Vatican 2 had different experiences.
To respond to you (chuck001) concerning how you responded to the OF, without knowing more and having an opportunity to speak with you, it is impossible to really respond to your comments effectively. perhaps a few points might provide some grist for you, however.
If I could provide that often used science fiction contraption of the time machine and take you back to the Upper Room for the Last Supper, I suspect you would have a very different experience from either the EF or the OF - and that, in spite of the fact that it would be Christ Himself as high priest. Given your experiences you would clearly be one-up on the Apostles as to understanding what you would see, but I doubt you might come to the conclusion that it was a Mass. A consecration, yes, But not an identifiable Mass.
And if you then “stayed around” in and out of time for several decades, you still might have a hard time recognizing the Mass, given that it was bifurcated over two days. Both experiences would be as authentic as authentic could be - one by Christ, and the others by the actual Apostles. and both exceedingly different from eithr the EF or the OF - far more different that the comparison of the EF and the OF.
The form of the OF - the entrance, penitentiary prayers, Gloria, readings, homily, Creed, Offertory, Epiclesis, Consecration, prayers after consecration, Lamb of God, Communion, prayers after Communion: all follow along in the same format in the EF. The EF has some prayers added, but the format is the same. One is in the vernacular; the other in Latin.
Comments are made about the EF being more “doctrinally clear” but as that is a catch phrase that gets tossed out with exceeding regularity, I find the comment unsubstantiated. Certainly with the three cycles of readings over three years, coupled with more biblical readings (aka the Old Testament), I don’t find the OF “doctrinally unclear” as doctrine comes to us substantially through the Bible (as well as Tradition). Certainly the EF has a different and more extensive ritual base, and may be more formalized, Beyond that, however, I can’t add comment.
