I think I got in right after the first movie came out; I had one of those "oooh, shiny!" moments and went to Google. The first fic I read was also one of the first D/Hr fics ever written, so I apparently had one of those duckling impression moments or whatever -- you know, where the first thing the duckling sees better be its mother, or it's going to follow it everywhere anyway. I got into slash a good bit later.
