Not eloquent at all, dear Glenn, only devoid of better-established English vocabs. Sorry for that, but now I'm back for a second try, and this time, I am armed with my faithful
Langenscheid dictionary !

It advices me to use this formulation:
A hype is to inflict/impose an information, not by giving evidence of the quality of the item but by repeating similar slogans again and again. Just like the golden rule of advertisement: "If you want to be succesful, pretend to be succesful already". That works very well in many cases. But there's a proportion of people who react allergic on that and tend to rather dislike the item until being given proof of quality.
Me for example, I will rather dislike Rihanna until I hear any good song of her, no matter how often her picture is imposed on my eyes. And I will consider the Lafayette escadrille overhyped because I know of their low tally. This will not change at all when more and more hypes like books, memorials and awards are numerated to me.
Let me quote a common anecdote from the country I happened to be born in, the GDR (quite difficult to translate, Langenscheid do your best!):
"A fellow received three awards: the first because he had none, the second because he had one only, the third because the had two already".
Cheers to all,
Michael
