This is his most consistent album in a decade, which is also a testament to how bad the albums inbetween were.
The concept works, the rapping is on point and he actually has some pretty funny bars on here. Hes making fun of himself and his public persona, which is more in line with his early albums.
The production works, you might need that Eminem sound for this type of album. I still think the best thing he could do now is get out of his comfort zone. He should give up some creative control and actually collab with a producer. Just stop trying to please everyone, and stop producing your own songs. I mean he sometimes does a good job, but its usually overproduced and almost any producer would do a better job.
