There's only one word to describe this film: SPECTACULAR!

Rating: 10/10 (23 November 2013)

Sequels rarely live up to its predecessor. But in this case, aside from the fact that it's adapted from the book, it's expanded. It's a start-to-finish entertainment. With a gap only for one year and eight months from the first one, This is a solid fare.
The movie continues the events from the first movie. Katniss Everdeen (the remarkable Jennifer Lawrence) is still struggling from her trauma of the 74th Hunger Games. She and Peeta (Josh Hutcherson), are presented to each district of Panem as the sole survivors. Katniss became a symbol to the people and causing them to start a rebellion. The president (Donald Sutherland) is conducting the 75th Hunger Games, named Quatrell Quell, and it's all up to Katniss on how to survive from it.
What's interesting is in the script. It is so unpredictable that it keeps your heart racing waiting for what happens next. It never goes downhill. Everything is slick and unpretentious, never boring. You'll see it.
I recommend you to see the first one because a lot of reference will be needed to watch this spectacle.
