i saw on twitter a screenshot (i forgot to save it, sorry) of an interview by localizers admitting that they've completely scraped the Japanese dialogue of entire scenes and completely changed entire story scenes before.
That's how bad it is. We need to look at Japanese games over the last decade or so and retranslate all of them i think
I'm OK with this if its something like ghost stories strangely enough. An already mediocre anime made funny is a lot better than what they do now. Even making fun of politics was fine there, why was this a once in a life time thing though? I never got that.
All anime and manga deserves to be faithfully translated regardless of the quality of the story.
The dub of the anime The Devil is a Part-Timer had a reference to Super Size Me in the first episode.
To my shock, it was also in the Japanese audio track...and the original light novel.
References to American media in Japanese media aren't rare. There's a reason Katawa Shoujo, a loving western parody of eastern visual novels, had a character just wearing Bush/Cheney For President T-shirts... Long after his presidency, both in development and in-universe. They like random Americanisms.
But those are their references to make, not the localizers'.
