I think I did see the same movie as you did I think the overall acting has gotten better, but the movies not necesarrily the best book adoptation is in my humble opinion still Azkaban... SPOILER ALERT DON't READ IF YOU STILL HAVE TO SEE THE MOVIE some minor stuff about this movie I would have want to see different: - when snape arrives at malfoy manor they should have had yaxley arrive at the same time as snape and have their little dialogue ( read the book for specifics) When they enter the main room where Voldy is , they should have shown that voldemort trusts snape a 100% by acting like he did in the book saying he should sit at his immediate right and staring him in the eyes showing the ferocity of the gaze whilest interogating him and show the little dialogue between Yaxley( explaining about the imperiused Pius thickes) snape and voldy, when Voldemort ask if anyone knows Charity ( the floating woman) snape answers ah yes with a mocking smile ( in the movie they showed his pain which could betray his allegiance and makes the character less believeable- Alan rickman is the best by the way ) - At Malfoy manor where they are captured and Dobby comes to save them, he shows no fear at all and acts like a superhero( for people who don't know this is where dobby was enslaved before harry freed him for most of his life and has been treated brutally), that and the damn sneakers ruined Dobby for me.. they followed the book so closely that i don't get why they didn't follow the book on this part. But all things said and done this was finally a good movie again, because the HBP wasn't that good rather bad actually and they kept out the main parts in favour of a collapsing bridge and some pick up scene in a subway and an attack on the burrow which never happened and didn't make sense at all... Ah well c'est la vie
