My review: All in all, I came away feeling... unfulfilled. Disappointed even. Reviews on the movie have gone either way; some people rave it is the best so far, some people think it fell quite short. I'm in the latter category. The movie itself LOOKS great. I cannot complain about that. The dialogue, to me, seemed not as good as usual... too jerky in places. Again characters acted in ways I did not expect. Lavendar was spot-on at some times, and totally over-the-top others (even more than in the books, I felt). Actually, thinking about it more and more, maybe she was pretty good in her role. Harry was in love with Ginny the entire time. THE BURROW BURNED DOWN. Ok, ok, I know I need to put canon aside when looking at a movie, but... ugh.
And there was a total lack of action. The ONLY part I really felt was truly epic was Dumbledore frying Inferi. Dude, when the zombie apocalypse begins I am totally calling on Dumbledore. However, the end of the movie pretty much sucked. Snape isn't shown to be a bad guy; he purposely doesn't attack Harry and spares his life several times. IMO in the tower he should have Petrified him (or it should have been like in the book, which would have been MUCH better). The worst injustice was there was no funeral scene at the end! The entire ending is so disappointing. It's just a nice sunset and a chat. UGH.
Neville has exactly two lines in the entire movie; once as a butler (added in to the movie) and once wishing Ron good luck. Out of all of Draco's friends, only Blaise is spoken of by name; and that's because the actor died while filming IMO.
That said, some acting is done really well. Luna's actress is GREAT in her role. I think she's spot-on, and probably my favorite character to see on screen. Harry himself didn't do a bad job. Slughorn's actor is the same guy who played Harold Zidler in Moulin Rogue, and I kept expecting me to say "Invest? Invest!"; however he should have been much fatter. Dumbledore was totally a mixed bag for me. First of all, he doesn't have his glasses in more than half of the scenes, including his death. I know it's a small point, but Rowling always made a point to talk about his half-moon glasses. That said, the character totally LOOKED the part of Dumbledore in my mind... but his voice grates on my nerves. I think it may be the accent (which I'm starting to think is Irish, not British) that has a habit of falling off at key moments. Also, Ginny (Bonnie Wright) looks a lot like Kirsten Dunst when her hair was red for Spiderman; anyone else see it? And I laughed that she was taller than Harry!
In conclusion, the movie felt like a 2 1/2 hour filler episode. Very little action, very little plot movement, but a lot of fun awkward teen romance stuff. It's not a BAD movie... it's just not a fulfilling one. And I wished for Levicorpus to be used! That would have been right in line with the humor shown throughout the movie.
Rating as a general movie: 6/10. As a HP movie: necessary to see, but probably will be the worst in the series.
