This year, I've actually seen everything in the Best Dramatic Presentation: Long Form Category.
I think my first choice is Batman Begins, despite my plotting nits. I would not be displeased if Wallace & Gromit in the Curse of the Were-Rabbit won. That movie is So Wrong in all the right ways.
The Lion, the Witch and the Wardrobe was a very good adaptation of the source material, again, despite my nits. What is this with Father Christmas not giving the Beavers a gift? Lewis knew better, and so should the folks who made the film. And, I really, really wish Lucy's moment of less than utter perfection, where Aslan chides her for delaying in caring for other folks, had been kept in. It fit thematically with a lot of what the movie was doing, as osewalrus noted: There are several places where someone isn't being evil, but is causing harm by being short-sighted.
Harry Potter and the Goblet of Fire was a good adaptation of a long book that really frustrated me, the epitome of Rowling being so good that it drives me batty that she's so sloppy. I think the third movie may have been technically better, but I'm not sure. The three things I recall now as bugging me are:
1. Dumbledore. He's furious with Harry? Fine. But, have him be furious like Dumbledore, not like an old geezer who's losing it.
2. When Harry hesitates to help Cedric in the maze scene, I'd forgotten about Cho Chu. mneme thought that a quick flash of her might have been useful, and I agree. Minor, this.
3. The villain should have been given his speech -- the "Did the Dark Lord kill those cowards who denied him when the going got tough?" speech.
I think, to my surprise, that the movie that most disappointed me was Serenity. Now, take this in perspective: THis was a very good year for movies, and I enjoyed the movie fine while I was watching it. But, afterwards, it seemed empty.
Part of it is that the background was tweaked so that people who hadn't seen the series might have an easier time following it, I gather. It bugs me that Mal, who made such a point of Simon and River being part of His Crew in the series, telling Simon, "If your sister doesn't risk life and limb, out you go." I really didn't like Book turning into the Ethnic Wise Man who Gives Good Mystical Advice and Dies. Bleah. And his advice? Have faith in something, anything. I'm not quite seeing Mal having faith in nothing, and, to the extent I am, well, it makes for an annoying and less interesting movie.
It isn't exactly Mal's movie, though. It's River's movie. And this, too, is a problem, because the movie focuses too much on Mal for it really to be River's movie, but too much on River to give Mal a decent shake. And Simon and Kaylee are fairly cliched and dull here. Oh, I'd watch a second movie or a new series, but there is less to Serenity than meets the eye.
