I've always taken reviews with a grain of salt. The white/rock focused outlets (Spin, Rolling Stone, Pitchfork, etc) are just not made up of people that I'm necessarily going to listen to their opinion of hip-hop. Sorry. That's not because most of them are white, but because it comes from outside the culture. I get an offensive vibe from them that they expect their musical innovations from black culture at a higher level. You see 10th generation garage punk bands be raved about like they're doing something new, but Stillmatic or whatever gets slammed for reminding them of something from 5 years ago.
On the other hand, I've learned that reviewing outlets within hip-hop culture can't always be trusted either. I'm sure we remember some of the awful reviews in The Source and XXL. A lot of this is based on favors and access to artists. Honestly I think that's why Yeezus has gotten so many good reviews. Say what you want about it (I think its borderline garbage), but let's say I'm wrong about it being bad. I've gone back on albums before. What I have never seen is universal acclaim for an album, particularly one as polarizing and with as much backlash as Yeezus. Let's think about this...All Eyez On Me, Stillmatic, The Blueprint, The Fix and a plethora of other hip-hop albums most would consider classics received at least SOME bad reviews. Yeezus hasn't, and I think its because hip-hop journalism is afraid to do it, and say what the vast majority of people think. Kanye is at a point in his career right now where he's bigger than hip-hop media, he doesn't even need them. Compare this to 808 & Heartbreaks, which while mostly acclaimed, was nearly as polarizing, and yet did receive some critical reviews.
Moral of the story: Use reviews as a guide, but judge for yourself.
