The german word "muß" is an old spelling, maybe its possible to replace the word "muß" in "muss" in every section

I think it's not necessary to replace all german overviews with some words of old spelling, because the words are still in use, and it's not changing the sense of the overview. And it's really impossible to do this for all german movies from 1900-2016 now, the spelling was right at that moment the movies were released, so I think they can stay as they were written

Not the answer that i want to hear but okay ;-)

So for the future, i dont report this kind of spelling mistakes?

Sure if there are great mistakes please report them and if you can correct it yourself, it's fine doing it. My special thoughts about this was thinking of all the old movies and the overviews or the spelling on the posters we should leave them as they are
