The movie starts out with a very ominous feeling and you can just feel the pain and loneliness that all of the characters are feeling. As things start to build, and the action builds very quickly, you get pulled into the story. I was a bit disappointed with the way Mad-Eye's death was handled, but I liked the improvements on Hedwig's. I'm a sucker for the twins, so I must say the Phelps brothers did a fantastic job and brought a bit of humour into the movie that would have left it otherwise quite depressing (which I could have lived with). The wedding was not a big part of the movie, but I'm glad it was included. They didn't have Harry in disguise, but I don't think it detracted from the scene at all. When the wedding received the notice of the Minister of Magic's death, things went crazy.Just as they should have.
Once the trio is on the run and they begin their search for Horcruxes, the movie starts to get slow. When Ron leaves, that's when things get to be a bit too slow (even for me). I understand that that part of the book is a bit slow, but I feel like there should have been more action. There were several scenes they could have added, but they didn't. And that's okay. It happens. When Harry and Hermione head to Godric's Hollow, things pick up again. The scene with Bathilda Bagshot... Creepy. As the story progresses, from here, its all uphill. Things are action packed. And emotional. And absolutely fantastic. When they're at Malfoy Manor, I got chills. And teared up during the torture scene. And the final scenes of the movie, I cried. Like a little kid.
All in all, I think this was the best movie adaptation so far. And it is just that, an adaptation. Some people complain that the movies don't stick to the movies exactly, but I think that's okay. I think it is fine to change small things, leave certain things out, add something if you think it adds to it (just not to the extent that they did when they butchered Half Blood Prince). I'm now trying to patiently wait for Part II
