" while he enjoyed the episode overall , stack wrote that spears ' songs felt forced into the storyline , and that the episode was neither as iconic nor as exhilarating as glee 's madonna tribute . the parents television council slammed the episode , accusing the presentation of spears as a " symbol of empowerment and self - esteem " problematic , observing that the young audience " basically witnessed an endorsement of narcotics abuse , public masturbation , and school - sanctioned burlesque . " james poniewozik of time , who disliked the madonna episode , was " pleasantly surprised " by " britney / brittany . " he deemed it one of the funniest and most entertaining episodes of the series , crediting morris ' performance and the " fortunately limited " spears cameos . responding to criticism of the episode , poniewozik conceded that the storylines were slender and spears remakes dominated the episode , however felt that unlike " the power of madonna , " it worked because " it owned its slightness : it kept the videos ( and britney 's appearances ) where they belonged as fantasy . " bobby hankinson of the houston chronicle described the episode as brilliant , and felt that presenting the spears performances as a series of unrelated hallucinations was " an inspired choice . " ign 's robert canning rated " britney / brittany " 8 / 10 , signifying an " impressive " episode . he described it as fun , but close to being " too much of a gimmick , " with incongruous song choices . vanderwerff deemed spears ' cameo " totally useless , " criticizing the singer 's " flat , listless dialogue . " lisa de moraes of the washington post graded her cameo a " c , " commenting " at least she didn 't have to try to be funny " as in her how i met your mother guest - spot . flandez was disappointed that spears did not appear for longer , yet he concluded that given the acting demonstrated in her 2002 film crossroads , it was better that the pop star did not . conversely , jenna mullins of e ! online appreciated the fact that spears did not appear as a background character , writing that she is " best when she is playing herself " , stack felt her appearances were well - handled , " with a nice level of restraint , " and canning felt they were kept to a " perfect minimum . " morris ' performance attracted critical praise , with de moraes calling " britney / brittany " a " great showcase " for the actress , praising her " spectacular dance moves " and " deadpan flare " . in his otherwise negative review , vanderwerff deemed morris " hysterical throughout " and the cast 's best dancer . he stated , " murphy seems intent on running this character into the ground , but morris isn 't going to have her stop being funny without a fight . " mullins observed , " when ryan murphy said this episode was a celebration of heather , he wasn 't kidding " , commending her musical performances . canning was initially concerned that the episode would diminish morris ' appeal by elevating her from a background role , but was ultimately pleased that it managed to retain her " fan favorite " secondary character status .
