And seemingly all the rest of Japanese tv consists of "What does gaikoku think about this aspect of Japan? Isn't Japan cool?" type shows. Either that, or "Let's go to gaikoku and be surprised and appalled because they do things differently than we do!" shows.
While I don't personally dislike Japanese TV, many people, especially in Japanese (written) media, have been pointing out that Japan's been plagued with an overzealous tendency to self-praise these past few years.
This phenomenon even has a name, "自画自賛症候群" ("jiga-jisan shokogun", the "self-praise syndrome"). And as you're pointing out, it's especially well represented in TV shows.
