How are they saying it wrong? What are they pronouncing wrong? Who is guilty of this the most?
Every single name is being mispronounced. Go check the japanese version or the anime and you'll immediately see how they say names differently. Except for Igor and Margaret, obviously. In that regard, it's them who say the names wrong, lol.
Yeah, no. Accents don't make pronunciations wrong. If you had something specific, I might actually be inclined to give you some credit here.
Of course they do. If the sound coming out doesn't match the originally intended sound, they're being mispronounced. How would you even argue otherwise? I don't care if the equivalent sound doesn't exist in english, it can easily be replicated and isn't being so.
Although I understand why you see it like that if your native language is english, spanish, french, german or italian. The fact that these are such dominant languages in their respective homelands means their speakers have so little contact with foreign languages they end up pronouncing every foreign name wrong and assuming it's ok. Dubs in general are the main cause of this (admittedly insignificant) problem.
I had a british foreign exchange student in my class a couple of years ago named Michael. Some people pronounced his name as "Mick-hail" because that's how our language's pronounciation of it would be. However, most of us said his name correctly even though it's sounds don't exist in our language, BECAUSE HIS NAME IS MICHAEL, not Mick-hail.
Much like Dojima's name shouldn't be pronounced Dough-jeema (and in fact it's proper enunciation is impossible to translate into english text). A name is a sound you call someone by, it's pronunciation isn't up for debate. There's one single correct way to do it.
Out in the real world it doesn't bother me. Hell, I live in London, everybody says my name wrong here and I don't care in the slightest! But in cases like this...
I wouldn't say it's expecting too much. These are professional voice actors, they should have no problems with properly enunciating things, regardless of language.
