I'm getting ready to finish Set 16, so I've got about 9 sets left to get through. Once I finish this watching of it I'll probably shelf it for a while and then start back up again. That's one of the only things I don't like about DS, is that I like to watch TV shows that I have on DVD all the way through, and it takes me soooo long to do it with DS. Not to mention the fact that with other sets like Buffy or Nip/Tuck, I know which eps I don't like so I can just skip them (though I still rarely do that) but with DS there are just too many!
When I finish, if I need a fix I'll probably just know to pull out this or that set because it's taking place during a certain storyline.
And I still need sets 20-26.
