I have totally become the same way recently when it comes to canon vs. fanon couples. These days, I pretty much always ship either canon or nothing because it's just not as satisfying to me to ship a couple that never becomes canon. Fic alone just isn't enough to satisfy me when it comes to ships getting together.

And totally agreed about Bones. I saw a lot of Booth/Brennan shippers on my flist thrilled with that plot twist after it happened, and I was just like, "...really? Because I think this is kind of awful." Amy's pregnancy on Doctor Who was similarly pretty awful. There's a pretty good chance I'll end up giving up Bones this coming season, which is saying something for me, since I pretty much never give up shows.
