Just because someone belts out a song at the top of her lungs (which every lead in this show does) does NOT mean they deserve a tony award! If that was the case, this entire cast would be up for Tonys!
Also, the half "standing ovation" she received after 'You Oughta Know" was very forced. Audience members did not know what to do when they noticed some of the stans start standing after the song, so these poor tourists stood up to join and it was very uncomfortable. It was by no means an earned, automatic standing ovation.
