The Rocky Horror Glee Show "Slant Magazine" called it a "travesty" and criticized "the arms-length treatment of the Frank N. Furter character", and Amy Reiter of the "Los Angeles Times" deemed the episode flawed through its sanitization, despite initially having found the two shows "a particularly promising match". "The Rocky Horror Glee Show" received several favorable comparisons to previous themed episodes; Erica Futterman of "Rolling Stone" deemed it the best yet. Both "Entertainment Weekly" Tim Stack and Jarett Wieselman of the "New York Post" preferred it to the Britney Spears tribute episode "Britney/Brittany"; Wieselman hailed it as a "run-away success" that would satisfy "Rocky Horror"
The Rocky Horror Glee Show Colfer re-iterated his desire to perform "Time Warp" at the 2010 San Diego Comic-Con International, which prompted Murphy to reveal that a "Glee" episode devoted to "Rocky Horror" was planned for the show's second season. At the 2010 Television Critics Association Summer Press Tour, Murphy stated he would be directing the episode, and also revealed that Adam Shankman would guest-direct one of the first ten episodes of the season. Shankman later revealed via the social networking website Twitter that he would in fact be directing the "Rocky Horror" episode, and commented, ""Rocky Horror", while really risqué, is perfect for "Glee"
