Well, I can't remember a w/r fiction that put me on such an emotional rollercoaster!
I was horrified at the sexual harassment endured by Rogue from Sabretooth, angry at any sort of romantic relationship between the two, frustrated by Wolverine's lack of action, railed against any humanity exhibited in Sabertooth, and then the ending came.
I was so wound up over the whole thing, I didn't know whether I liked it or not.
Then I realized that's exactly what an author is supposed to do: don't spare them, don't treat them like children, take them on a journey that challenges everything they think they knew.
In the end, this really was an amazing story. And I'm so very glad I read it.
Job well done.
