I just finished the Hunger Games trilogy yesterday evening.
Wow....I have never found a series that engaging since......Twillight.
Once I started on Book 1, I was practically reading any chance I got. And kept bugging Simon to pass me the next, pass me the next! :)
I can't say much for the ending. I feel it created to allow for what Katniss did.
I like who she ended up with and the reason why she ended up with this person.
If you have never read this series, it's a good series to consider. And read it before you watch the movie. There seldom is a time where a movie potrays a characted better than words.
