It's a dope album but I just think in this time frame music is consumed so differently. I think the combination of it not being GREAT (ie like Dre's old shyt) the era and the hype of whatever project Dre was going to release next made for a negative tint on the perception of the album.
I think that can be a good thing though, kinda like getting that quick nut out the way so you can really beat shyt up.
Dre no longer has to worry about super sky high expectations when he drops his next project. He's still legendary and an icon but I think this album getting some luke warm perception makes his next release easier.
What he really needs is to break a NEW artist. His greatest moments have come along with ushering in some of the most unique talents in Hip Hop history. Kendrick probably been that for Detox but that moment never came. He was already established and looking how shyt played out with Rakim and The Firm it seem like working with artists who are pretty much finished products make for better conversation than it does music.
For Dre to truly have the effect on the genre that WE (old nikkas) are used to seeing him have he's gonna have to once again use an album as a launch pad for somebody FRESH. And unlike rappers who need to be center stage he can still do that when he's in his 60's, we're going to get another burner from Dre eventually. But it won't be with him rapping on every song like Compton with features from finished products.
