@JGoldman10,
MovieGuide is a Christian review site. They seem to give ratings on which movies are ok for Christians.
Here is what they said about Frozen
"Very strong Christian, redemptive, moral worldview stresses love is sacrifice, family, scenes in a church with a church choir, a song about loving people even with their faults..."
And Frozen II
"Strong, somewhat allegorical Christian, moral worldview with an emphasis on sacrifice, doing the right thing, there’s a line about the need to pray for safety, marriage and friendship are extolled, love casts out fear..."
Both films got positive reviews.
As explained many times, the millions of other Christians are not strict in their beliefs as you and your family.
