I thought that I already understood many of the intricacies of Japanese social norms, and this series took me by surprise. It isn't easy to understand why things develop the way they do once Moguro offers something to the episode protagonist.
Imagine one of those episodes when Nobita comes crying to Doraemon for help, and he offers a gadget but also a warning, and Nobita just plainly forgets about it or ignores said warning, sometimes out of greediness, sometimes wanting revenge towards one of the bullies. Doraemon has a soft spot for Nobita, he believes in Nobita's good nature as a child, and when Nobita gets what he deserves, there's a chance he will learn from the experience. There's a moral to the story, and you will see Doraemon at the end of the episode being angry at Nobita for not listening to him/being a brat, of feeling pitiful for him, sometimes even laughing at him for being Nobita.Well, Moguro knows what the person in each episode is like, he knows how to lure them to take advantage of what he offers them, I mean, it's a trap from the start, and he gives a warning that will end in an "I told you" situation. Everyone in this series is going to get punished, it doesn't matter if the person deserves it or not, and feels like the moral is not to trust anyone that is offering to help in any way (and this is mostly a Japanese mindset, that nobody helps without wanting anything in exchange).You see, Japanese people are way too rational in general and have a hard time reading the intentions of other people. There are way too many victims of fraudsters, cults, conmen, and swindlers in Japan, because the majority of people learn there is a certain way one should behave in society.There is more to that general 'teaching', of course, each main character shows a different aspect of human nature: how they are greedy and are not happy with what they have already, the way many of them have a weak character, the lack of ambition, sometimes excessive complacency. Even characters you think maybe don't deserve the punishment, there ¡s something that makes them lack virtue.In the end, the series is about what the problem with each main character attitude is, and what it may lead to if you keep going that way.For the 'NEW' part, I think it is a good way to make Warau Salesman known to younger people, but aside from offering extra episodes, it doesn't add anything special to the manga or old anime.
