ok how about another album that critics legitimately underplayed the opinion on until it turned out to be a huge classicI don't know where you get that from. 808s got positive reviews everywhere. NPR gave it a good review.
oasis "(whats the story) morning glory"
after people really liked definitely maybe, people were thinking whats the story wasn't as impactful and more generic and lackluster.. then it turned out to sell gangbusters and end up being possibly the best (or at least 3rd best) britpop album ever made... so much that when be here now came out all those critics gobbled it up so hard when in retrospect it turned out to be considered horrible
