And so it did. Release, I mean. And let me tell you: this was the best Harry Potter movie. Ever. According to me, of course. It was hilarious. It was dark. It was scary at times. It was fast. It had some bits added, but these bits were still good [e.g. the scene where Hermione asks Harry, "Is this what it feels like? When you look at Ginny?" and the waitress scene at the beginning].
Bad points? There were some ... It lacked action. No Hogwarts fight. Added in the Burrow burning [why?!]. Did not show Tom Riddle looking for places/things to hide the Horcruxes in. Ron and Hermione were simply there to be comic relief.
This is a good place to go if you've read the book, and want to know what you'll love + hate in the movie.
