You are an asshole.
People who enjoy things, enjoy them and rate them highly. Those who don't enjoy things those same things don't.
At what point does overrating kick in? Or perhaps you're arguing that your subjective opinion of any given work should be normative for all people everywhere, and that those who rate them higher than you are therefore overrating that work.
The word overrated itself suggests there is a set standard. By calling something overrated you are asserting that your own standards are the definitive ones that all others should measure works by. Tell me, what about you made you into the grand appointed judge of a works oh-so-clearly objective quality? Who are you to tell everyone that they shouldn't enjoy something because you don't? Especially based on your own personal feelings?
If you enjoy something, you enjoy it and that's OK. If you didn't enjoy something, or find that it doesn't live up to the hype and you didn't seem to enjoy it as much as other people, then that's your own personal feeling and that's OK, too.
But to call something overrated makes you a pompous. Self-important. Asshole.
Give yourself a pat on the back.
