I seemed to remember the sixth book being about the journey through Voldemort's past via several memories. Some pertinent information was lost due to the lack memories in the movie. The possible existing horcruxes were not explained to Harry and there wasn't a battle at the end! The last two movies have got some catching up to to do when it comes to plot.
With all that being said...
I loved the movie. I understand that film adaptions take liberties out of necessity. If JK Rowling okayed this movie...then so be it.
The relationship woes, the brilliant acting and the captivating story; it all gains my joyous approval. I'm going to take off my critical hat and go enjoy the movie for a second time.
