AIBU not to let my three-year-old watch Frozen yet?

[Colourfulrainbowunicorns]

A discussion came up with a bunch of mum friends and I was definitely in the minority. I thought I would post here to see if I am being unreasonable. It's fine if I am.

My DD is 3. She has become aware of the character of Elsa from Frozen at nursery and loves this character. I am not bothered by this and happily got her an 'Elsa' dress when asked. I also allow the songs.

I will not however let her watch the full film.

She gets a bit invested in programs and is easily upset. She also likes to properly understand 'why'. I think there is a LOT of explanation and unpacking needed in Frozen and that she can wait a year or so.

On a practical note she doesn't have the concentration to watch a full length film like that.

DS was 3 when it came out, DD was a few months. It was the film they loved the most (never seen the two of them sit together to watch anything else like that actually). DS was most concerned about the parents dying, being without mummy was always the thing that worried him. DD learned quite early on some things about relationships and toxicity: she initially liked Hans because he was a good-looking prince, but she soon realised that you can make a mistake just going for that in someone. I don't think these were bad lessons to learn. I think the whole thing about Elsa being different and shunned is probably again a good thing to learn from, and to not treat people badly for being different.

It's always the case on threads like this.
