While I understand your point, it would seem logical that there are folks in the world who are new viewers who have NOT seen the demo a million times - and who are looking for a product for their needs.
For those of us who have seen it so many times and are really in the market for this product, then we've probably already ordered - will order - or not ... and wouldn't really need to be re-watching the demos.
Truth is, there is nothing anyone can do to truly describe the "real" scents of the Graces, etc. Ya gotta trust and try ...
