I like some of her books, but I am quite annoyed with kids most of the time coming from poor families with missing father/mother, it's like she couldn't write a book without some tragedy, of course the most famous Emil of Lönneberga and The Six Bullerby Children are from normal families (there is probably reason why these are the most famous and beloved), but already Pippi Longstocking is pretty F-ed up and don't get me started on The Brothers Lionheart, which is glorifying suicide and should be really banned for kids under 15, certainly not appropriate for 9yo, though I read it to my younger kid with appropriate commentary.
I didn't appreciate Pippi Longstocking fully until I read Stieg Larsson's "Girl with the Dragon Tattoo." Occasionally covers are better than the original song.
It's perhaps no coincidence that the opening theme song of the Fincher (Mara/Craig) version of the movie is an outstanding cover of "The Immigrant Song" by Led Zeppelin.
Kids do think about death. Hiding or avoiding the discussion does nothing. My kids absolutely adored Brothers Lionheart.
>>which is glorifying suicide
I've literally re-read it this year again and I couldn't disagree more, like, to a point where I wonder if we even read the same book. That book made me scared of dying when I was a child, and it made me appreciate the finality of death again now that I'm a grown up. There's nothing there that "glorifies" suicide - we could have a meta 2026 conversation about whether it's trying to say that yes, terminally ill people _should_ be able to decide what they want to do with their own lives, but that's not the message the book is going for(imho) - it's about bravery and loyalty even through the darkest of times, and about sacrifice(not suicide!!!) that comes from standing up for what you believe for. I don't personally believe in afterlife, but just as much as I loved the idea of naningalia when I was a child I still love it now - it gives children hope that even in the darkest moments of despair, there is something better waiting for them. The main character literally dies of ilness at the start, being bed bound for a long time without his loving brother and mother who doesn't know how to help him. The fact that he chooses to join Johnatan at the end in the trip to the "next" level of afterlife couldn't be further from glorifying suicide.
Remember that Astrid Lindgren was born in 1907, got pregnant at 18 and had to give up her son to a foster home for the first few years. She grew up in a completely different world, and it's no coincidence that a lot of her stories are basically about consoling traumatized children.
