Well i used to believe that too. I mean i watched Rurouni Kenshin, Naruto, Blood+, Claymore, Spice and Wolf and Death Note etc. But even so its usually a case
when they really feel like adding it in. Although there are some that actually have respect to not use some chibi, but thats usually rare.
Well its more optimistic in the cases. Like they dont try to make it melodramatic, its more here it is. Enjoy, type of entertainment
Not from what i remember. That stuff is very very noticable in japanese animation.
