Do you know what consensus means? Since judging if something is great or not, especially when it comes to games which is very opinion based. The "greatest games of all time" or developers have to be judged based on what the averages say so if you ask 1,000,000 people what their favorite game is and 900,000 say Zelda OOT for example, then based on the consensus that is the greatest game of all time it's irrelevant what the other's think in that case, because consensus says it's that. So if you ask if rare is overrated and most people say no they aren't overrated then they aren't overrated because most people say they aren't. It's pretty straight forward, it doesn't mean you have to like what the average says, but the law of averages say that you are wrong, you're an outlier.
TL;DR You don't have to agree with the consensus or like Rares games as much as others, everyone has their own tastes, likes, and dislikes, but the consensus is that they are (were) great, therefore not overrated.
