I remember everyone was hissing at the Baroness, and one girl behind me was shouting "Oh come on, she's not that bad!! She's not that bad!!"
He loved Maria and clearly preferred her over Baroness Schrader.
While watching The Sound of Music, I wondered if the Baroness was supposed to be a villain.
She definitely doesnt seem to have any interest in the children (she mentions sending them off to boarding school rather than being a mother to them), and this definitely seems to paint her in an unfavorable light.
This idea of a widowed father marrying a woman who doesnt like his kids makes me think of The Parent Trap, in which the prospective bride was definitely the villain of the piece.
However, in The Sound of Music, I dont really think shes supposed to be evil (even if she does trick Maria into going back to the convent). I think shes just the wrong person to marry the captain, and her role in the movie is to be an obstacle to the captain and Maria falling in love (after all, if they fell in love right away, the movie would have been much shorter). So, while shes not a character you root for, I dont necessarily think of her as a villain. What do other people think?
