Both the books and the movies affected me the same way.
The Hunger Games is exciting, it's something new, something I've never seen/read before. It's filled with action, suspense, fast paced, intriguing, and ends on a high.
Catching Fire is slower paced, interesting, shocking, exciting because you get to meet past Victors. At the same time, you get to see the district's people reaction towards Katniss.
The second movie was the one which made me read the books. The cliffhanger was just too good. I just can't wait to know what's gonna happen next.
Mockingjay, this is the serious stuff. The part where the struggle is real. If you don't like politics and don't enjoy movies about politics, or you're that person who just don't give a damn about politics, you won't enjoy it at all. Highly comparable with our political scene. Fewer action, somber, low key compared to the previous two books/movies. Even with all the stuff happening in part 2 (after Peeta was rescued) the overall feel of it was sadness and devastation. A happy ending but it didn't end with a bang like what some viewers/readers expected. I think, that's how it should end. That's what Katniss was craving for after living a hectic and tragic life.
In short, it can be quite a bore because it started with so much energy and ended too calmly but it's not bad if you can relate to the main characters and not just look at the general story line. I initially preferred Gale to Peeta but that changed after Mockingjay, especially because of the delayed explosion plan that killed Prim.****
