If you're looking for another short in this vein, consider checking out The Long Long Holiday (currently on Amazon Prime Video). Great family show that definitely works for adults. It's a miniseries exploring life in occupied for a couple of kids set during WW2.

The Voyager crew are war criminals. Janeway especially. She's perhaps my favorite Trek Captain (top 2, probably), but there's no need to warp the historical record to show them as war criminals, only to show them as worse war criminals.

Would love to have seen animated miniseries "The Long, Long Holiday" make this list. It has the Avatar-esque quality of making you ask "this is for kids/families?" and yet you still sometimes is actually age appropriate, despite some of the topics it deals with (which is kids growing up in occupied during World War 2).
