Just got out of a screening of King Kong (a day before release, nyeah, nyeah, nyeah).
For my money, Jackson has hit it out of the park again. It is not too long at 3 hours. (Just over 3 by my watch, before the credits start, as opposed to the just under 3 claimed by the studio.)
Lots of nice touches. Oodles of amazing set pieces. Laughter. Tears. Pathos. Giant bugs. And you gotta love a movie that puts screenwriters in cages.
