last movie of harry porter

i have saw the movie days ago, to tell the truth, several details are not showed well in the movie, i felt puzzled after seeing it.

my dear friend yes at last harry survives and voldemort gets defeated, I think you must watch the movie I can't tell you the climax how voldemort gets defeated, voldemort has stored his life in six horcrux to gain immortality. Harry gets married to Rons sister Ginni Weasley they blessed with 2 sons and a daughter named James Sirius Potter, Albus Severus Potter and Lily Luna Potter

Everyone who's read the books knows - and there's probably a long synopsis on IMDB if you want it.
