Different when the Brothers Grimm were writing their stories?
The biggest thing that came to mind that I noticed first, was dialogue from different characters might be in the same paragraph. I'm so used to having dialogue of a different character on a seperate paragraph, that reading dialogue like this feels a little weird. Then other times the dialogue was written as bullet pointed dialogue.
Less serious of course, is how the stories felt summarized. Though I'm not sure if they would have been improved much, by showing the whole infodump at the beginning. (An infodumps an infodump, show or not.)
