Such a beauiful, artistic, and creative movie!
My daughter is 11 years old and her favorite movies are ones that require focus and inference to understand and there honestly aren’t many that are as clean as Donnie Darko. There is a lot of vulgar language, but not gratuitous or unmotivated. The violence is a little shocking. The romance is beautifully depicted, consensual, both sides extremely respectful of each other and very loving. Of course, you have to know your child. If vulgar language and scary voices/characters are upsetting to your kid in general they will not like it. If your child doesn’t like to feel confused and doesn’t want to “figure it out” they will not follow the subtle artistic nuances and probably find it dull. But if your kid enjoys that type of thing I think it’s a great movie to show them. Point out the use of imagery, the color pallets, the love and the mystery. It’s a great movie, my 11 year old thought it was amazing.
