Yeah i have to say i was disappointed. I did enjoy it, i just feel they didn't use the time they had effectively. The focus on Ron's bloody love triangle shit me to tears, there is no where near that much on that in the book, it became a major plot point and it shouldn't have. Then there was Harry's developing relationship with Ginny, which was not illustrated anything like it was in the book. The amount of focus on the teen romance drove me insane, in my opinion it just feels like a blatant attempt to compete with Twilight.
I think the thing that made the amount of romance so frustrating is that it was included in place of the important memories and gathering of information about Voldemort and the Horcrux's etc, which really is what it should have focussed on, Voldemort taking over the world is in my opinion slightly more important than just how obsessed bloody Lavender is. And like somebody already mentioned, the burrow scene was pointless and didn't even happen, i do not understand what would possess them to just add that rather than include the dramatic fight scene that really does happen at the end of the book at Hogwarts, i was looking forward to that, but rather we watched half a movie of Draco putting things through the vanishing cabinet, so the death eaters can get into Hogwarts only to do nothing more than stand and watch, they played no significant part, and was a little frustrating.
It was just the comination of so many of those little parts that took so much away from the movie as a whole.
Overall i just really don't think the movie was a fair enough portrayal of the book, it really didn't do it justice, the priorities were just all wrong. But still, despite all of that, there was still a lot of good in it, and i did enjoy it. If they cut out the pointless scenes (ie, any scene involving Ron and Lavender) and replace them with memories and developing pieces of information on the Horcrux's etc, it would of been great. It's made me a little concerned as to how they are going to go with the last book to be honest.
