The anime is funny, but it does go a bit deep into relationships and how they are. For little kids, they won't be able to recognise it but for older viewers, you should be able to realise that the realtionships in the anime are quite deep. For example, Sailor Uranus and Neptune are more than friends, they are actually lesbians. There isn't any thing wrong with it, but this is just one of the mant relationships in this anime. It's really good the anime and is fit for all ages.
