The cheesy over-sexual choreography, the attempt to make a song like OIDIA sensual, the rehashing of yet another Britney song, the deadpan expressions on everyone's faces, the fact that most people simply don't care about Glee's existence anymore
i will save the performance for the episode.
But the cover is amazing, i just can`t at Lea pull some vocal superior on a song like Oops, her high note is amazing.
