I saw it last night in a completely packed out cinema (having spent the last two weeks desperately counting it down I was late and almost missed it altogether..) and I have to say I was well impressed.
As you may or may not know, the final book has been split into two films; this is the first half, and the second is out next July (something else to start counting down to...)
I won't bore you with plot details, because I'm going to assume that anyone going to see it has most likely
Their acting skills have most definitely improved. Ron and Harry's fight, followed by Ron's departure, was really well done, and even Emma Watson has toned down her over-acting of Hermione. She seriously impressed me during the scene with Bellatrix in Malfoy Manor - those were some crushing screams. Hermione and Harry's friendship is also touchingly done, particularly after Ron leaves.
Its not all tissues at the ready though; there are some funny moments, most of which occur at the beginning and can be contributed to the ever excellent Fred and George. "Saint like", anyone?!
One thing I wasn't happy with was the lack of time spent in Grimmauld Place at the start; I know that for the plot to progress to the fast paced stuff they had to cut it reasonably short, but I am a major Sirius fan, and I was looking forward to Harry snooping around and finding out a bit more about Sirius's past. Overall though, this was definitely the best of all the films, in my opinion, and I absolutely cannot WAIT for the last part now. The film does end on a cliffhanger; fair enough, you don;t generally find natural endings in the middle of books. A few people are grumbling about this, but I personally would prefer a cut off point and have the film stay faithful to detail (which this one does, more so than previous films) than rush through things to fit it all in. Its still a solid two and a half hours of pure entertainment, and now you have another one to look forward to!
So to summaries ... GO AND SEE HARRY POTTER AND THE DEATHLY HALLOWS!!!
