OK, so just watched Gone Girl.
It's a very, very impressive movie.
It has a really tight narrative, containing a labyrinthine plot that throws your perceptions around at an alarming rate, yet at the same time never feels convoluted. At 2 1/2 hours the pace never lagged once and I was pretty much transfixed to the screen. A lot of this is of course down to the acting and it has a great cast all round, with Affleck again showing that he does have a some depth and gravitas. However, it's Rosamund Pike that completely steals the show. Now as you can see by my previous post I didn't have much time for her in anything else but in this she is utterly and completely fantastic. One of the most intense and superbly nuanced performances i've seen for a while. Can't go into too many specifics without spoilers, but I genuinely didn't know she had it in her and she deserves every single plaudit she gets.
The direction is as expected excellent from Fincher, who ditches many of his more obvious visual flourishes in favour of a solid storytelling style.
I only have a couple of quibbles really - One is the portrayal of the media which I found so cartoonish that it bordered on parody and the other concerns a few scenes with NP Harris, but again it's difficult to explain with spoiling anything.
So, overall rather excellent.
