Previous Harry Potter films followed the highlights of the storyline so the viewer who hadn't read the books got the gist of the story. Details that were important to the storyline but contained in ancilliary dialog in the books were incorporated into the movie a little differently. For example, in HP4, the movie doesn't mention the cash prize to the winner of the tri-wizard tournament. In HP5, we see that Fred & George have opened their own magic shop funding not mentioned, yet the book tells us Harry provided the $$$ with his winnings from the TWT. Also, the romance between Bill & Fleur is minimal, we see them at the departure from 4 Privet Drive, then at their wedding, again we get the highlights to advance the plotline for the movie and not the details in the book. There was more detail in the book about the problems at the Ministry of Magic that lead to its eventual takeover by Voldemort's followers. The movie indicates that happening, but the focus is on other events, as it should be. HP 7.1 was well done. It does get a little dry as we follow Harry, Ron & Hermione's trek through the wilderness while they try to find the other Horcruxes. The movie does end on a good 'to be continued moment'. It does a good job laying the groundwork for the climax of HP 7.2; for which we anxiously await.
We enjoyed the movie overall. Some of the interactions between Hak Mun Rah and his minions was a little dull. Hank Azaria did a great job filling that roll, especially using a 'boris karloff' impersonation as Hak Mun Rah. Ben Stiller, Owen Wilson, Amy Adams and others did a great job, as of course, did Robin Williams as TR. The CG was very good.
