The Hunger Games: Mockingjay Parts 1 and 2.
The first two were not exactly brilliant, but they were entertaining enough. Decent waste of a couple of hours.
But there aren't enough words to express my intense dislike for the last two movies. So incredibly boring. Barely anything happens. The decision to separate the last book into two movies was a major disaster, but even if it was just condensed into one movie I can't see how it would improve all that much. The story id just horrible. The first two movies were building up to an epic battle and what does the last movie show us? Nothing. We get to see what happens AFTER the battle - which could be interesting...but it isn't.
I was so f**king bored out of my mind, especially watching the last one. My girlfriend who loved the first two movies, and even liked the third one hated the last with a passion.
