"The Odds Are Never In our Favor"

I recently saw the movie MockingJay Part 1 and i thought it was a piece of art. So i thought to myself, Why not read the book? I've read Hunger Games and Catching Fire, but i decided that i wasn't going to read the third. This was because of the responses i heard about the book from my friends. They said "Don't read the book" and " It's sooo boring". But I read it anyway.
I regret it...
The book (in my opinion) just drags on, and has very minimal dialogue. There are pages and pages of description which gets tiring very fast. Now I'm not saying the book is a bad one, all I'm saying is that the book is tiring to read. I feel like the series has gone downhill. Hunger Games was exciting and grew curiosity. Then Catching Fire came out. It seemed a bit repetitive with another game. And i felt that it moved a bit slower. And MockingJay had a pace that I didn't enjoy. But if we were to put that aside and just focus on the story, then this book is great. The story has a lot of unexpected parts, and the ending was a shocker!
