The beat is sick and Em does what he does. Some fans are complaining that Eminem's doing "that white boy ish", but uhm, it's either sound like this or like Paul Wall. Even Tina Marie doesn't sound black, bless her heart.
I don't have a problem with the song; it's totally Eminem, and either you like him or you don't. Or like me, you're pretty indifferent and won't hear the song again until it comes on the radio and only then, after hearing it over and over, will you know if you like it or if it gets on your nerves.
