Re: Signs + Others. I think that if the driving factor of a film is fate (or faith)...it's hard to have a true DEM. An exception that I can think of, though, is the self-acknowledged DEM in Donnie Darko.
Mike, The end of the Stand wasn't really a DEM, because it had direct ties to the plot. The film(book) is about faith, and that's how it played out. Not to mention the fact that they weren't exactly saved by the hand of God...the hand ignited the nuclear bomb and destroyed Las Vegas.
Richard, Trinity may not have the same power as Neo, but that's not why she was able to bring him back. It was her fate to love the One, by admitting it, and therefore fulfilling her fate, the One was reborn, because he can't be dead and the One at the same time. At least that was my take on...
