What part of rues death was missing from the movie

Book version: Rue is speared by a boy from District 1 while still in the net before Katniss can cut her loose.

Movie version: Katniss frees Rue from the trap, but then is killed by the spear after a sense of false hope.

Significance: Makes her death all the more saddening. Much more dramatic and uses the opportunity to give Katniss a less-hard side to her personality.
