 The girls ' Bon Jovi – Rolling Stones mash @-@ up was received favorably by Stack and Milzoff — the former graded it " A " , the latter called it " brash and fun " , and both writers appreciated the black leather costumes . While Harper also liked the costumes and the energetic performance , she felt it " paled in comparison " to the last mash @-@ up the girls performed , in the season one episode " Vitamin D " . Futterman commented that the costumes and choreography overwhelmed the vocals , to the point of being " a little too Miley and not enough Glee " . Benigno called the song a " cacophony " and gave it his lowest performance grade of the episode , a " D " . He suggested that Glee had been responsible for " reviving the mashup fad " , but hoped the girls ' performance would serve to end it again . The boys ' Supremes – En Vogue mash @-@ up was graded " A " by Stack , who liked the combination of artists . Harper preferred the girls ' costumes but felt the boys gave the better performance , while Futterman found it overly @-@ sentimental in context , but also preferred it to the girls ' song . Benigno gave it a " C " , and commented , " Not quite the debacle the previous mash @-@ up was , but given how fantastic this episode was , the sendoff should 've been better . "
