Series

So, as you know I've been reading Rachel Caine's Morganville Vampires series.  I never intended to go on a YA vampire book reading binge, but for some reason when I read a few books in the series I can't stop.  I need to finish the series.  And, the books are alright--some in the series better than others, but nothing I would probably re-read again (I don't mean that in a bad way, it's just that I need to reeeally love a series to re-read it again). Early on in the series, and even later books, she leaves a ton of cliffhangers at the end of the books.  If I was a reader waiting for these books to be published I would be annoyed because I don't like when authors manipulate you into buying their books via plot tricks. Anyway, it would bother me if I quit a few books into the series.  Is anyone else like this?  Once you start a series you have to finish it?

Now I finished book 11 (even though there's two more books which will have to wait) and I think I'm going to move onto something with more substance.
