OVERRATED
Granted, there are far more egregiously used, and over used, words today. Including, but not limited to, 'literally', 'like', 'hate', 'bias', 'strawman', etc.
However, the demeaning, dismissive, and overly pretentious nature of 'overrated' has reached near mythic proportions nowadays. We even see a sort of subculture of egoism that bases its entire existence on considering anything remotely popular as being "bad" or "not worth its praise"; regardless of any actual merit the material may have.
Get rid of this word, and suddenly you'll find the pretentious neck-beards of the world actually having to work for their sense of self-superiority.
