An overrate means to value or judge something as being better than it really is. You might do this when you're so excited about an idea that you think everyone will love it.
When people talk about movies, music, books, or even restaurants, they often use "overrate" in everyday conversations. For instance, a friend might say, "I know some people overrate the new Marvel movie – it's just okay." This usually means that their expectations were really high and what they got was slightly disappointing. Sometimes, when someone says you're overrating something, they mean you're exaggerating its good qualities or ignoring its flaws. It's like being too enthusiastic about a concert and saying it was the best show ever, but others might not agree that it was that amazing.
An excessive estimate or rate.
To esteem too highly; to give greater praise than due.
