hypekill 

The phenomenon in which a film, album, book, or other work strikes you as less good than it actually is, because of the high praise it has already received from mass audiences before your first chance to experience it.

"Everybody told me that movie was so great and I had to go see it, but I was kind of disappointed. I guess I fell victim to the hypekill."
