Top Ten Tuesday: Series I really should finish

There are a lot of really great series of books out there, and like many of you, plenty of series I've started but never made it to the end. I thought that I'd join up with The Broke and the Bookish this week and list a few for you.  In no particular order...

1. The Black Dagger Brotherhoodby J. R. Ward. A local friend even loaned me her copies and I never made it to the end! They were really good though, and I really want to get back to them.
2. The Dresden Files by Jim Butcher. I was flying through these until we moved, and then I seem to have lost the one I was in the middle of and never bothered checking the library for it.
3. The Hollows by Kim Harrison. I love these while I'm reading them, but as soon as I put them down I forget about them.
4. Weather Wardens by Rachel Caine. Are we seeing an urban fantasy theme here? Mike loved these.
5. In Death by J.D. Robb. I'm making real headway on this series. I think I'm somewhere around book 36 with only a handful left. I don't read the novellas.
6. Kitty Norville series by Carrie Vaughn . I have no explanation for all these urban fantasy series, except there are just SO MANY of them!
7. Anita Blake, Vampire Hunter by Laurel Hamilton. And honestly, I won't finish this one, too many characters and too much going on to reacquaint myself with.
8. I gave up on the Stephanie Plum Novels by Janet Evanovich. The one good thing about them was the humor, but even that was getting stale and repetitive.
9. Diana Gabaldon's Outlander series. Ok. I never finished the first one. BUT I WILL. (I'm looking at you, Andi.)
10. The The Hunger Games by Suzanne Collins. No, I never read 2 and 3, and I want to! Somehow they are never the most compelling books on my shelves.

What about you? What series are you stalled on? Is it because it's boring or outdated or because there just isn't enough time? Should I be jumping back into one of these?
