But presumably not as much as the people who overrate it, right? Surely you can only consider something overrated if you don't agree with the people who rate it most highly. And if that's the case, then all calling something overrated means is "I don't like it as much as some people", which is going to be true for everyone in 99.9% of cases; Ergo, calling something overrated is pretty meaningless.
This isn't an attack on you, I just hear the word "overrated" thrown around a lot by hipsters, and if there's one thing I hate it's words with no useful definition.
Also, I thought the Beatles were significant because they earned every ounce of their hype by being genuinely creative and influential.
