I started my blog after seeing these two films, but they are both nominated for various awards so I'll post a quickie review of them.
PIRATES OF THE CARIBBEAN: DEAD MAN’S CHEST is a very weak film. I liked the first film a lot, mostly because it had a good sense of humor about itself, and Johnny Depp gave one of the most creative performances of the year. The second film in the series takes itself MUCH too seriously. Depp has much less screen time, and the writing is very weak. It did not make me want to see a third one.
MISSION IMPOSSIBLE 3 was terrible. The whole series has been weak, and this is the weakest of the three. You'd think the addition of a good actor like Philip Seymour Hoffman would make a positive difference, but the writing was so weak, he had nothing to bring to the film. The direction was also very weak. You'd think a scene with a guy dangling from an airplane would be scary, but when you shoot it all in close-ups, any threat of falling is removed.
