The movie blog Movies from Every Angle posted a sort of state-of-the-movies manifesto earlier this summer that is worth taking a look at. Here it is, in four (or should I say, IV) parts: Part I; Part II; Part III; Part IV. It has some interesting insights about the current (as well as past instances of) trends towards remaking movies. For instance, there's a particularly astute observation regarding how the makers/distributors of these movies have started to shy away from the term remake in favor of "reboot," or "reimagining."
The blogger at Movies from Every Angle, Michael Brody, was also quoted in a recent AP article about the strategies being used by movie theatres to compete and attract customers in this new streaming-video, hi-def, iPod age.
