[28] Meanwhile, The Independent gave the album two out of five stars, stating that "if [it] was conceived to let Mathers have his cake and eat it – to indulge his earlier, purposefully offensive wordplay under the guise of struggling against the Shady persona within – the reality is the worst of both worlds.

"[31] In a review for Cult MTL, Mr. Wavvy called The Death of Slim Shady (Coup de Grace) Eminem's "strongest album in over a decade, which may say more about his abundance of misfires since The Marshall Mathers LP2 than it does about the quality of this body of songs.
