This sequels pacing and feel are so much different than previous films. Thankfully the change is a good one. The whole focus of the film is on character development and story. All the visual effects are incidental and integrated completely into the story. In other words there no dazzling CG effects for the sake of having eye candy. Many of the previous films follow this same idea, but not to the same degree as this one. Thankfully the slower plot of the film isn't so slow and uninteresting to the point of pure boredom. There is constant interesting things all along the way. One particular high point of the film is with Dobbie, who makes a renewed appearance at the end of the film. The CG and acting are worlds better than his first appearance. All in all this film is well done to a superb artistic level beyond previous films. But it is quite long. Plan on two sittings for the well Done Harry Potter and the Deathly Hallows: part 1.
Also, this film is well deserving of its PG-13 rating for multiple deaths/murders, torture and disturbing imagery. Not for little ones under the age of 13 for sure.
