I really enjoy reading the Peanuts. They're kind of weird sometimes (sometimes Snoopy talks, sometimes he doesn't) but I like all the characters, they're all relatable in some way or another. Exploring the world around them is fun when seeing and hearing things through their simple conversations. The character's are drawn lightly and simply, they're easy to take in. The beauty of the Peanuts is they appeal to everyone, though it seems they're target audience is younger children and adults.
I have heard a lot about Little Nemo but never read any of McCay's work until now. I love the large format, it really fits the content of the comic and kinda of puts the reader into a "child-like" way of reading the book (the size makes me think of when I was younger and books seemed so much bigger than me). The consistent format of the comic (how he always falls out of bed at the end) is something I normally wouldn't be attracted to, but found myself really enjoying. Though I don't feel super attached to any specific character really (Nemo is rather dull himself, more of an observer than an adventurer) the crazy things that tend to go on around him are interesting enough to keep me reading.
