I thought I was going to be in a minority in regards to the rape scene. I'm not sure if it was a "mistake" per say, but it was one of those "we could do this but should we do this" type moments. It's one thing to push the envelope, but when you have an entire season where you're pushing the envelope, where is the line. I think they did cross it.
I was thinking about waiting until tonight to post this, but I couldn't sleep last night and I ended up seeing Villains. I know about Dark Willow and Spike going to recover his soul now. I couldn't believe how dark they made Willow, just because of Tara's death. Considering the amount of care the show took to deal with addiction, it was a death of a loved one that made her not only go back but become a lot more powerful. Warren was a waste of space, but that scene where she takes his skin right off was shocking to say the least. As for Spike's soul mission, this was why I quoted your post. I get the feeling after the attempted rape and now that Spike really didn't know what he was doing and was mad at himself for doing it. Do I condone what he did? Absolutely not. Still, this direction in the character really isn't as sudden if you understand the journey he was already on. It almost seemed like what he did was the tipping point, positive or negative.
