> [...] because I also feel dubbing in Germany comes out pretty much right.

You've got to be kidding me, lol. Anyway, voice (character) mismatch is the first thing I often notice. How often have I heard a commanding adult in English dubbed into what sounds like a tortured, overemoting teen/twen in the German version (I feel it's especially pronounced in women's characters but that might be just sample bias). Even deadpan delivery sounds tryhard. And it's not just for English, either.

Modern German dubs, to me anyway, are their own comedic genre. And make no mistake: I'm fuckin' serious about it. Just study some classics. You'll see.
