It's hard to describe what I think of Moomin. Moomin and his family live in a kind of fantasy creature alterworld, where they are most of the time at peace with nature and without need. Their small dramas are generally caused by their falling into absurd misunderstandings of the world, and their relationships are innocent and loving. But there is also a very crazy anarchistic streak to characters like Little My who enter that world and cause chaos that the other characters try to cope with in a sort of bumbling, childlike way. The Moomins also live like unreconstructed hippies, doing whatever they please in the world and interacting with it spontaneously. There's an emphasis on nature and the seasons and food and relationships and all the fundamentals, and Moominland delivers a very appealing worldview, philosophically. It's sort of nuts and 'out there', but also very pure. But I think also I just really love her drawings. Each new character is drawn as something formed completely differently from all the others, a shape and a face you wouldn't expect. She has lots of super simple, clear and direct lines, very expressive and sort of warm, somehow. Her drawing style is recognisably of its time and place (Scandinavian) and maybe this adds to its charm for me as well. Those little crinkled foreheads do a lot of work in the faces. Even the way she draws objects and houses and things is super super sweet.
But I'm making it sound too nice: it's a really wild world, this one, actually.
