Well, sometimes it comes from racism.
XD Mostly, though, people don't like it because they think it is cartoon. (from the looks of it; though anime seems more advanced in the drawings)
Some of my friends (usually Koreans and Chinese -rarely Mexicans-) have a certain feeling towards the Japanese. My sister's friend's mom feels as though her daughter might abandom their Chinese beliefs from being obsessed with Japan. I also know a Korean named, Minjung, who hates the Japanese. When she sets her eyes on an Asian that she thinks is "ugly," she would say "Is that a Japanese person!?"
I think it is pretty disturbing, but lucky for me, I have unbaised friends to support me. They were also Koreans so they could've easily said that the girl that Minjung thought was ugly is in fact a Korean. (which was true)
Well, yes, I guess its KIND OF because of racism of Japan's history, but I'm not sure if it is the main reason people judge it horribly.
(Um... I haven't heard much about Japanese people being racist. I don't see WHY they would even be racist. I think they base their racism if you are a beginer/tourist. Other than hearing that information, they seem to welcome you nicely. I'm thinking that it was only because of the past history of why people are against them. If you are nice to them, they will most likely be nice to you.)
