Wow this was bad (compared to the book)

Rating: 2/10 (3 October 2015)

First: Battle Royale VS. Hunger Games...
I'm not going to comment on this. I did see Battle Royale some time ago, but my intention here wasn't on comparing those 2 movies.
Second: I usually don't read books... I'm a lazy bastard and usually prefer to simply watch a movie... But because of all the hype on Hunger Games, I thought I'd give the book a try. And to be honest: I loved it. I loved the characters, I loved this whole 'poor districts vs. wealthy Capitol'-part, I loved the actual 'games' and many other things.
But this movie... wow, that was bad o.O How did it get the 7,3/10 when all the reviews I'm reading are like 3/10 or worse? After reading the book and while watching the movie I noticed that so many good and important parts of the book were skipped here. It seems like a student's poorly done recap of a book he only just read on the bus on the way to school.
By poorly done I mean: - e.g. their fire-costume at the beginning... while reading the book I was like 'woah... I'd love to see that in reality (in the movie)'. But when I actually saw it 2 hrs ago in the movie I thought 'ehmm... that's it? that's some lame CGI-work'. - the characters (e.g. the other participants): they are barely mentioned. Some of them are shown/named, then the next scene shows their (rather quick) death and that's it... forgotten... - the control-center scenes. Oh my God - I had to mention them... those are so bad. Did they hire a trainee and let him do a quick work in 3D Blender?
I'm sorry if my review isn't as detailed as many others here - but so was the movie. I'm just so very disappointed that I had to post my (very first) review here. I thought about watching the other movies and skipping the reading-part (lazy bastard, you remember...?) but I'm just too afraid those movies are as bad as this one and that I might actually miss a good story.
