I think she is entitled to her opinion

but if she does want to be closer to God it is a strange way to go about it. But then St. Paul was a bit odd in how he got close to God.
God works in mysterious ways so you should not get disheartened by what she says or does but rather Pray for her and know God does his thing. Who knows there may be something in the show that may provoke something in her. Someone may make some jokes about the Crucifiction and this may stir things for her. You do your bit and let God do his but keep her close and be ready to lead her with the wisdom, patience and perfect timing of the Holy Spirit.
