Most movie series suffer from diminishing returns, with sequels dying slow painful deaths rather than going out with a spectacular finale. They rehash tired concepts, rely on gimmicks rather than good writing, drain the concepts pool completely and frankly, “thrash the dead horse” endlessly. Prometheus showed us that the Alien/Predator series should have died five movies ago... But when it comes to Bond, James Bond, the 007 formula works in complete contradiction to the diminishing returns theory. Skyfall is one of the best constructed, acted, directed, photographed, written, etc. etc. movies this year. I haven’t been this excited by a movie since Inception.
