This is an album for kids whose parents bought them a paintball gun for getting straight Cs.
He says about 10 times across this album, this is music for middle schoolers. When someone tells you who they are, listen. Through some combination of nostalgia and perceived "technical skills" as a rapper, it seems this album has had some lasting power. But I'm sorry to say this is real dumb guy shit.
The documentary "The Merchants of Cool" does a good job explaining how this kind of music was pushed to middle-class suburban kids in a calculated, coordinated way by MTV, Viacom, and their corporate allies. This brand of crude, violent, gross, sexist machismo was one piece of a larger marketing campaign that included Jackass, Tom Green, pro wrestling, nu metal, South Park (and yes, Eminem actually does a Cartman voice on this album), etc. designed not only to reach young boys, but also to reinforce their warped perceptions of masculinity and gender. Eminem constantly flexes how he clawed his way up from the trailer park through sheer force of talent, like he was somehow at a disadvantage in hip hop because he's white when the opposite is obviously true. Eminem is white privilege incarnate because the forces of racial capital hoisted him into our faces to appropriate rap's popularity and profitability while erasing any/all subversive Black elements that may have "corrupted" white America. This is music of tightly controlled and contrived controversy -- Eminem says a lot of "edgy" things and he's more than willing to make a brave stance out of beating up women and gay people, but he can't be bothered to say anything that genuinely upsets power structures.
There's a lot of money and industry power behind this album so it's unsurprising the production sounds well-made. And a lot of hay is made about Eminem's "flow" and his "wordplay" and other supposed indicators of his rap genius. I can't and won't deny he can play the instrument at a high level, and credit granted for creating the concept of the "Stan." But I still don't enjoy the sound he makes. I'm a grown adult whose listened to a lot of music, read books, watched movies -- I understand what it means for an artist to "play a character" and that not everything that comes out of Eminem's mouth is a literal or direct expression of what he believes. I think kids who listen to this music also understand, on some level, that they're listening to a comic book character. That doesn't mean I have to find that character compelling and I still think it's worthy to judge whether the juice is worth the squeeze; is Slim Shady saying or doing anything so artistic worthwhile that it warrants verse after verse of rape threats?
