Don't you think that, if the answer is BCE, then the clue should probably be "Pre-C.E." (although, admittedly, it couldn't possibly be), and not "24A: Pre-A.D."? Well, I think so. In other areas, we have ENOTE crossing EMOTE, YSER alongside ETNA, and other distasteful things. EDO, EON, ETS...
The theme of mass commercialism is fine I suppose, although not symmetrical, but overall I had a terrible feeling about this one. Several clues rubbed me the wrong way, and, well... you get the drift.
I liked the word SCRAPES, but is it really equivalent to "just gets?" I know the actual clue is "43D: Just gets (by)," but it just seemed slightly off. I'd rather have either "scrapesby" in the grid (which, honestly, wouldn't be good), or a clue like "abrades," or "run-ins," that doesn't RELY (71A: Fall back (on)) (!!) on a damned parenthetical add-on. Also, 4D: Fill to the gills (SATE)? Isn't one more like "stuff," and the other more like "satisfy?" It was little stuff like that that turned me off.
