In the movie, I was really surprised at how little food Katniss was shown eating...

It's called "The Hunger Games" for a reason... they only had a few shots of her eating in the arena, like the groosling with Rue. Also there wasn't much in-arena hunting :/

And did anybody else think that the first scene with Gale and Katniss was awkward? They had little chemistry (the actors) IMO.
