Ever heard of the cognitive bias known as the availability cascade? Basically, it goes: Repeat something simple and superficially insightful, and repeat it long enough, and at some point it'll be accepted as truth. You wanna know what's bad about having a stupid, bombastic opinion early into an album's release? Rushing to judgment urges other people to rush to judgment, which then creates a wildly curved and inaccurate consensus, which can then drive the direction of would-be artists. That direction? To create contrived, first-impression classics. Also, it's just a conversation that makes us all stupider.
We weren't so quick to call every album a classic.
