Well, I finished the series. I'm glad I read it all. I had a few issues with MockingJay - though I do feel it wrapped up the trilogy well. 
 (view spoiler)[This book had the biggest kick in the teeth for me when Prim dies at the end. I cried for a solid 10 minutes. Finnick, Boggs - I was prepared to lose all of them, but not Prim. Everything after that kind of didn't really matter. I'm glad she ends up with Peeta and I find their relationship very plausible. But there is so much lost at the end. 
 Overall, I felt that for most of the book Katniss was just wandering around clueless a little too much. I would have expected her to take a more active interest in what was happening. I know she was a pawn in all this, but I did expect her to figure out a bit more and have someone to talk to about it. (hide spoiler)]
