I don't understand why they couldn't go with a male actor this time. In fact, that's what I thought they were going to do -- target the tween demographic by casting the teen heartthrob of the moment.
My gripe with female Peters is that no matter how talented they are, they just can't pull off being a boy convincingly (i.e. Amy Poehler at the Golden Globes when she pretended to be the illegitimate son of Harvey Weinstein). They overdo the machismo. On stage, you can get away with such things like overacting and gender-bender/color-blind/age-blind casting, but TV/film is not very forgiving.
Salve, Regina, Mater misericordiae
Vita, dulcedo, et spes nostra
Salve, Salve Regina
Ad te clamamus exsules filii Eva
Ad te suspiramus, gementes et flentes
O clemens O pia
