I'm not really the right audience for Doraemon, I suspect. Like, it's a series of silly, whimsical adventures aimed at small kids. The back of the book even has an "explanation" section that describes the theme each chapter is built around. As an adult who wasn't born and raised with the cultural background, expectations, and assumptions that are built into the storyline, I was never going to have the easiest time just letting go and experiencing those adventures or feeling that whimsy.
But dang, the world of Doraemon is a nightmare if you sit back and think about it. Beyond the fact that its underlying assumptions and references are multiple generations out of date, Nobita's father is a stereotypical office grunt who barely seems to interact with his own family (who smokes inside the house! Yuck!). His mother is generally hands-off to the point of being ineffectual even when her child is clearly in danger, but is also quick to anger when things don't go how she wants. Nobita's "friend" group contains one girl who the author never seemed to think was important enough to give a single personality trait to, and two nasty bullies whose fallback pastimes are to torment or even physically beat Nobita. Doraemon himself is a selfish, childish, forgetful thing who seems at least as likely to unthinkingly cause problems - or just steal dorayaki from the family - as to actually help.
The only major element that's not worse than I had imagined is actually Nobita himself. Maybe other incarnations flanderize him into parody, but in this book at least he's far less of a hopeless nebbish, and far more of an ordinary kid, than the series' reputation suggested.
In the end, this book gets an extra star for succeeding at being exactly what it set out to be, but there are better books with better lessons out there that you could spend your time on instead of this one, regardless of the intended audience.
