9/10 Better than the first one, as expected.

Warning: Heavy spoilers for people who did not read the 3rd book!

It was better than the first movie on many points, especially the ones I expected it to be. But it still has some flaws, besides the obvious ones the first movie had as well.

First off, the obvious ones: Both movies fail to capture the scale of Katniss' inner stife concerning Peeta and Gale, and the influence of the home front (especially her sister and the role her mother had in the family.) I think this will severely lessen the impact of her sisters death in the final movie in 2015, just like it reduces the relationship Katniss has with her two 'boys' to a more common love triangle than it actually is.
In defence of the screen writers: it is hard to picture this strife on screen without getting long voice-over monologues, drag the movie out too much and make it boring. Since this choice was already made in the first movie, it was only logical they continued on this path for consistency.
- Secondly, the movies lose a lot of strength for people who did not read the books. This is because of the lack (or scarce amount) of background information. For non-readers this makes the basic outlines of the story a bit farfetched. (Why are there hunger games? What does the capitol wants to protect besides its own decadence? How come the districts didn't revolt earlier? These are a few questions that are easily asked, but not properly answered.)

Plot Development:
That being said, the 2nd movie manages to picture the cruelty of the capitol a lot better than the first one. This makes sense from a storyline perspective, since from this moment on Katniss gets more aware of the full scale of the oppresion in all the districts.
They stay true to the book, without getting to much attached to it. Maybe the first half (the victory tour) is a bit rushed, but that's understandable to avoid stretching out the movie too much.
Personally I think the movie needed 10-15 minutes extra to create that extra bit of (emotional) impact and explanation for a few things (like said earlier) or leave out a few scenes completely. Examples are the jabberjails in the arena or the replacement of the old peacekeeper. Also the conversation Katniss has with President Snow in her Victory Road home was too rushed, and lost its impact.
They managed to make some parts of the story even more clear, and the ending is way more satisfying than what Collins did originally. Less open-ended and more of a step-up to the next movie.

Acting:
Except for Donald Sutherland (President Snow ) I thought all the actors did a better job in the follow up movie than in the first one. It was obvious that they grew into their characters over time. Especially Elizabeth Banks (Effie) was exquisit and the faces Jennifer Lawrence (Katniss) did were top notch. She might be a bit too sweet and confident for Katniss, but she pulls it off. Also new character Johanna Mason, pictured by Jena Malone, was a really good casting decision.
The actors managed to give strong emotions to their characters, while they impressively managed to avoid overacting. Something that could happen easily in this story. They also got a few whimsical lines and responses in there that will make you smile.

Visual:
CGI were great, as expected of a modern high budget movie. They did not overdo it, which is a compliment for movies with this allure nowadays, and looked realistic, sharp and terrifying. Great job especially on the subtle way how they made the poiseness mist look. The only CGI I did not enjoy was the Tsunami (so the wave ON water, not when it came out of the forest.) This felt a bit cheap.
You notice the movie is by a different director, but nothing changed dramatically. Again, he jumps from 1 situation to the other a bit fast in the first part, and convo's are a bit cramped in because of the relatively fast scenes with information. So this can feel a bit messy. To make up for this, the arena scenes are detailed and beautfull. There are some interesting peek-throughs (deep shots) that keep the direct environment visible, and even one from a first person perspective. Not a fan of some of the close-ups though, they felt a bit cut-of at times.
Oh and costumes, great costumes that is, but A LOT of costumes :P

Sound:
I didn't really get up in your face, but managed to get the theme through to you at the important parts. Since I haven't paid attention to it in particular, that's all I have to comment on it unfortunately.

Enjoyment/Overall:
Great movie to watch, just like the first one. Has a good balance between action, stories, character development and originality. Depending on what kind of movies you like, the first half could be experienced as rushed or maybe uneventful, but the second part makes up for it in both cases.
All the flaws mentioned earlier are for the most part minor flaws, and do not compromise the movie for the most viewers.

ps. There were 2 'beeps' for the f-word when I watched it in cinema. I am interested if more people had this, and if someone knows if that will be on the DVD/Blu-ray too. Usually those words ain't censored in my country.
