Two different series...Two different books...Same feeling.
They both left me clutching the first two books, sobbing "WHY? Why did they do these to two perfectly good 1st and 2nd books?!" Both final trilogy books made me feel stabby. They were both well written books but left the series unsatisfying. Mockingjay had too many dangling wonders...like well, Gale. And although Maggie Stiefvater can say its not a cliffhanger...you can roll a duck in mud and call it a pig but if it don't squeal but quacks, the dirty thing is still a duck.
