We went and saw this on Saturday. I hate going to the movies. There are spoilers in this, and they will not be individually tagged. I don't want to hear about it.
In general: A thoroughly enjoyable movie. The story seemed to hold together given what was cut from the book, but as with H2G2, I couldn't tell if it would still have made as much sense if I wasn't able to fill in the blanks myself. But I support the filmmakers' decision to lop off most of the beginning of the book, since the Harry Potter books cough and splutter at start-up more than old Epson bubblejet printers. The elf rights storyline has also been painlessly removed.
Daniel Radcliffe as Harry: This boy is getting f-i-n-e FOYNE.
Rupert Grint as Ron: A very convincing, if annoying, sulky Ron. But the hair was terrible and he looks like he has mono.
Emma Watson as Hermione: The girl does all her acting with her eyebrows. There's a particularly grating part of the movie where she's yelling at Ron for not asking her to the dance in this incredibly forced choked-up voice, and as soon as she storms off we cut immediately to a scene in which she's using the exact same voice to yell at Harry about not having figured out the golden egg. I think Emma spends at least half the movie with one eyebrow raised and her jaw two inches off-center.
Robert Pattinson as Cedric: The guy looks a lot like Zack. I was sad when he died.
Stanislav Ianevski as Viktor Krum: Not ugly enough.
Clémence Poésy as Fleur: Not hot enough. Nowhere near bewitchingly beautiful, which I guess isn't such a big deal in the movie since they cut out everything about the magic hot women. I didn't remember her being so much of a wimp in the book.
Katie Leung as Cho Chang: I haven't been exposed to enough Multikulti to be comfortable with an Asian girl speaking with a Scottish accent, but hopefully that will come with time.
Ralph Feinnes as Voldemort: Solid gold. I'm glad they gave him human eyes instead of big red snake eyes. He clearly needs to breathe through his mouth since his mask covers his nose, but other than that he played the role perfectly. Ralph Feinnes is awesome. And despite the fact that he's bald and reptilian, he's still kind of hot.
I'd see it again, on DVD, as far away from a movie theater as I can get, with their 2:15 "evening" shows and extortionary ATMs. Please see this blog post for a discussion of everything that's wrong with the movies that's astute and vicious in a way that only Kenny can be.
