These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Americans Hate Tingle: Sazae-san is virtually unknown outside its home country. In fact, those who do know about it are usually Otaku, who view the show quite negatively for its perceived "blandness" and for its association with the elderly mainstream Japanese population (which, as a whole, is known to look down on Otaku and the anime fandom in general).
Archive Panic: Over 6,400 5-minute episodes, and the number's still growing.
It's Popular, Now It Sucks: While very obscure outside of Japan, some hardcore Otaku who know of Sazae-san and its mainstream popularity in Japan resent the series for various reasons related to this. For example, Sazae-san being labeled as a stereotype of what the elderly conservative majority in Japan wants all anime to be like (combined with their general marginalization of Otaku), which was especially prevalent when Tokyo mayor Shintaro Ishihara introduced the Youth Ordinance Bill.
Recycled Script: Most of the stories are based on the original run of the comic strip, and are rotated through every few years, only slightly updated with current clothing and technology. New stories based on current events are a rare treat.
The Scrappy: Wakame. Translated from a Youtube comment: "I think I'll have grilled onigiri for lunch. How futile. If everyone hates Wakame so much." By the way, there's a pun in that comment, if you couldn't tell. It has to do with Wakame's name
Values Dissonance / Fair for Its Day: Much of Sazae's home life seems quaint by modern standards, and even in Japan, the series is enjoyed primarily as nostalgia for the Showa-era boom times. This is in contrast to the comic's postwar origins and Sazae's (for the time and place) extremely liberated, feminist views.
