I went to the midnight showing last night (under the condition that I would go to school today) and while I was dead all day and yes, I may have taken a nap in study hall, it was so worth it. If you are a Harry Potter fan, either the books or the movies, go see the movie right now. Now. I mean it. Get online, go to the website of the nearest theater, find the closest time to right now, get in your car and go. Got it? Now stop reading this and get to it.
If you have seen it, and you didn't like it, please keep your comments to yourself because I thought it was Brilliant with a capital B. While yes, a few of what some may consider "major scenes" were taken from the film, it still stuck the the book almost precisely. There were even some points at which lines were taken from the book verbatim. And, beyond the fact that it was just flat out amazing, the cinematography was top knotch.
Favorite additions to the movie: Dance scene between Harry and Hermione; Animated version of "The Three Brothers"*
I really want to re-read the entire book now. It's been so long since I read it that I didn't quite remember everything. I'd only re-read up until the three are preparing to break into the ministry, so for the rest of it I only remembered brief parts.
Also, I would like to caution anyone going to see it: Pee before you go! There is one scene where, even if you're expecting it, you will still jump. I had to pee so badly that I nearly peed my pants when it happened, so please take care and go to the bathroom before the movie.
Also, contrary to what some left the theater believing, Harry and Hermione are not, I repeat NOT, a couple. Harry likes Ginny. Hermione likes Ron. Harry and Hermione are best friends and think of each other like brother and sister, and as such feel the need to take care of one another. When Hermione is sad, Harry tries to comfort her to make her feel better and vice versa. They're just looking out for each other. As for the scene with the horocrux, Ron feels like he's not good enough because he's best friends with, well,
Harry Potter. That little scene plays out simply to explain Ron's insecurity and worries. Nothing more.

I have felt ever since the first movie that the characters have always been cast well. Scrimgeour is probably the only character I never had a clear vision in my head for when it came to appearance, but after seeing the movie I feel that Nighy was a good fit. There were not many other new characters to be introduced this time around, but as always Daniel, Emma, and Rupert stole the show. Helena Carter shines as Bellatrix Lestrange,
always the creep but perfect in her role of bloodlust. There is just something about her that makes her perfect for that role...
Anywho, go see it. I've been obsessing over it for days, and I have no doubt that, if you like the movies/books at all, you will be too.
