This movie was surprisingly true to the book, given David Yates' prior track record with the Potter movies. I do regret, however, that he left out Harry's internal struggle with choosing between the Hallows and the Horcruxes.
Also, Yates has rarely included scenes with Harry's invisibility cloak in past movies. I guess he hasn't figured out, yet, how to do that particular effect. Seems like the cloak should have, at least, been mentioned, though, considering it is one of the Deathly Hallows.
