I liked how you mized in the fictional character with the actual script from the movie. Its unlike any other story I've read. Good Job!
Author's Response: Thanks. Glad that nobody minded me placing a character into the script. SG345
You've made one mistake that makes your story uninteresting: you just added one character and did not change the flow of the story. The orcs would have seen fresh meet in her and would have tried to kill her. Let her be rescued by the Rohirrim and knowing nothing about the hobbits would have made the story much more interesting. You would not have to use the dialogues from the movie and were free to tell your own story.
Author's Response: It does go out of the movie scenes in the next few chapters. It's written so they don't meet just yet. I kinda got into the idea that she sticks with Merry and Pippin for a bit. Then... well you'll just have to read on if you want. I've already written eight chapters on it, but am working on the others. I would change it, but I can't because it already has a certain flow to it. Otherwise I would change it. Saxongirl345
This is a nice twist on the Girl in Middle Earth trope: you found a girl who really can survive in Middle Earth. It's a very good start to your story, also, since you go right into the action and drama. The one thing that I think you should do to avoid the charge of Mary Sue-ness for Brunhilde is to take out that she sings so well. The character doesn't need it: she's good at other things, and wouldn't she be a little more piquant if she loved music but had only a so-so voice? (Think of Elizabeth Bennett in Jane Austen, who plays the pianoforte but makes mistakes, unlike her technically more proficient but far less charming sister Mary.)
Author's Response: Thanks for reviewing. Glad that you like it. I actually didn't mean to put the singing part in, it was for another story and ended up in this one, but I'll fix it up. Thanks again.
