This was... Ok. It's disappointing to have to admit that the finale of The Hunger Games is no more than "Ok", though there were redeeming moments that brings it to just more than a three star book, in my opinion. It simply lacked the spark and ingenuity of the previous two books. A few of the plot points were incoherent, or seemed superfluous or (alternately) not described enough.
It's funny - sometimes I consider a three star rating to mean that the book was very enjoyable, better than expected. In this case, it's actually disappointing. I guess those three stars are a little hard to quantify.
