Cinderella’s Forebear 
Man with morals   AESOP
Parent who minds how her kids act?   STAGEMOTHER [I thought goats, etc.]
Start to foam?   STYRO
Frosted flakes   SNOW
SNOW + WHITE summarizes theme and ends puzzle 
“We’re out of choices”   OTHER [is part of the clue missing --- if not it makes no sense] 

Obviously Patti does not share my distaste for all but the most common foreign words and terms in English crosswords:
Ano Nuevo month   ENERO [Why isn't the clue 
mes de Ano Nuevo?]
Torino time period   ORA [in English, it is part of the eye] 
Paella ingrediente   ARROZ
Stop in Quebec?   ARRET [clever, if you know French]   
RATING:  
Three grins = Excellent: Loved it; Two grins = Good: Enjoyed it; One grin = Satisfactory: A bit bland for my taste; One teardrop = Unsatisfying: No fun
