I have only read one but that one was Rumpelstiltskin. I read the one where it was not as grim but then for my performing arts class we read the more gruesome one and I found more interesting then the other one.

I have the complete collection of Brother's Grimm Fairytales. I absolutely love Cinderella's dark version.

Grimm's Fairytales
 

I just got the Complete Grimm's Fairytales. I've noticed several things about the stories contained within.

1. They all contain common themes. Marrying princesses, magical items, et cetera. A lot of stories even use the exact same themes in a row. For instance, one story will be about a girl with extremely long hair who can't speak, and a King rides up, finds her beautiful, asks her if she wants to marry him, and she nods. And the very next story I read will have the same thing in it.

2. Our ancestors seemed to be severely lacking in logic. In fact, they seemed downright insane.

3. However, some stories seem to have more logic, common sense, and empathy than others, which suggests they may be more recent.

Aren't these stories fascinating?

Yes..yes..they are. XD ..lol Yeah..silly ancestors! =p I have Grimm's Fairy Tales too. :3

They are pretty fascinating. I've noticed that about the themes, like you said. It's actually pretty common among fairy tales to be downright similar, but with a few details changed. This is where the Aarne-Thompson Classification System comes into play.

I just recently finished a Brother's Grimm book. It was a special edition and had a bunch of omitted tales at the end. My favorite story is called "How Some Children Played at Slaughtering". Very strange and sadistic short story, but it made me laugh.

I love reading the Grimm Brothers,
and their stories are definitely not for children. Haha.

My favorite would have to be Little Red Riding Hood.
