He released, from the consensus I've seen, a very mediocre album
Big shocker, everybody's said that for every record Eminem's released since Relapse (which legitimately did suck). Recovery was good, Marshall Mathers LP 2 was good, Revival was good, Kamikaze was good, MTBMB is good, people are just salty and bagging on Em's new stuff is always the cool thing to do for some reason
This one has a number of killer songs: Unaccommodating, Godzilla, Darkness, Lock It Up, Farewell, No Regrets... young fresh guest appearances, slick modern beats, so many great verses, rhyme schemes, TONS of hilarious and clever wordplay, it's a real good record.
