D.E.M. implies an implausible [to the audience] save; and there is no value to that. The minute the audience finds a story development implausible they lose interest; this is the point when they turn to the back to see the final page number so they can compute how much more time they must waste to see if the sub-plots are resolved better, or if they should just give up. As mentioned in another answer; the DEM of the Greeks were _not_ implausible to the audience: They believed in Gods and were seen as a time-saving device; as in "this is how it would all work out". Kind of like the "much later" post-script of some movies (e.g. When Harry Met Sally; with the two of them elderly and clearly married happily ever after). The best equivalent to DEM that can still be used is seeding the implausible solution in the opening act, while you have the benefit of the audience's willing suspension of disbelief about _anything._ You can introduce magic, interstellar travel, telekinesis, telepathy, whatever: You can also demonstrate real life implausibilities: show a six year old winning a junior archery championship, or an eight year old successfully solving differential equations to the amazement of their PhD tutor, or using their phenomenally photographic memory at the behest of a parent _that takes it completely for granted._ Now to some extent, these kinds of things force the story to be about those things; but you can also take a few notches off "perfection" to establish an unusual ability or character or coincidence that can serve where you thought the DEM had to be. If the story demands something implausible; establish it very early in the story where it will be accepted as part of the foundation of the fiction. Once the first Act (the setup) is over the author has spent all their credit for implausibility. If more is needed, rewrite the first Act: But of course it cannot go on forever, and there are limits to how much implausibility the audience will tolerate, even in the First Act.
