 Hankinson , despite his criticism of the episode , liked " Love Shack " so much it was his favorite song of the episode , and Futterman called it a " well @-@ executed note " on which to end the show . Both Lynch and Slezak said that Blaine failed to project the campiness the song required , and that they were glad Kurt took over from him . Their grades were quite different : Slezak gave a " C − " , while Lynch , who complimented Mercedes as well as Kurt , bestowed a " B + " . Chaney was more enthusiastic than both and gave the " rousing " cover an " A " : she was enthusiastic about Criss " bebopping all over the place " , and also noted that " the most entertaining all @-@ company performances on Glee are the ones where it 's clear how much fun everyone had during filming " .
