Anime humor itself isn’t annoying (often weird, but not annoying). It is the when and what that makes anime humor annoying. Anime has the bad habit of interjecting humor during serious scenes and having characters that are more annoying than funny.
Fullmetal Alchemist Brotherhood is especially prone to injecting humor during serious scenes. Several times throughout the series Ed or Al transform into a “humorous” character during series scenes. It was so common it become expected and ruined the scenes. Humor is important and has a place…at certain times. Otherwise it can be jarring and ruin a scene’s impact.
Anime humor is jarring as it is. Abruptly switching to a chibi character or another stylized form (sometimes they are not even characters, but chairs and other inanimate objects) can throw off someone not used to anime’s…idiosyncrasies. Anime humor is often frantic and perverted too. It definitely has little place in key scenes ...
