There should be a difference between "children movies" and "family movies" as two different genres on IMDb. Otherwise many people might believe movies like this are movies for little children and won't even try to watch it. And in the case of Ronja it would be as big mistake as if you avoid watching "Deer Hunter" if you don't like war films, or "Godfather" if you don't like crime movies. Certainly Ronja is not The Godfather, but it's one of the best in the genre: you should have no prejudice - this movie has no age, interest or other limits.
It is not a "children movie" as most movies sorted in "family" genre are, like "Pippi Langstrumpf", "Madiken" or "Alla vi barn i Bullerbyn" (all of them by Astrid Lindgren books). It is not a movie you have to watch because you are a grandparent who has a duty to watch TV with grandchildren. It is a movie you can watch at any age alone or with any member of your family. I watched it with my children who are from early to very late teens (and you know how at that age kids try to get as distant as they can from childish so nobody could consider them to be little children); I've never seen it before and it had no sentimental meanings to me (no memories from my childhood), but we all loved it and still, months later, laugh remembering some scenes or quotes. And I saw my wife crying as she never does watching standard tragic stories like "Titanic". We are not that old to be senile and back to diapers. So, if we all loved it - isn't that an example what a real family movie should be?!
So please, could these two genres could somehow be distinguished?
