I find a lot of darkfic kind of infatuated with the same sort of angst, which is really not my thing. I don't mind sad stories -- I think "If You Are Prepared" is brilliant, for instance, and it's both dark and an epic -- but it has to be really, really good to impress me that way. *g*
I was a Remus/Sirius and Lucius/Severus shipper at the start. Somewhere after book five, I switched allegiances. *g*
