And I think you can compare them, an overused plot-point is an overused plot-point, why should we be more accepting of them in superhero titles? Doesn't that demean the genre?
Here's the difference:
We know that Bru employs the overused plotline to provide a quick, overly neat ending to his story; he does not innovate the explanation of the fake serial killer in any way. By contrast, we don't know yet how Snyder is going to use the good-guy-turns-bad cliche. If he uses it simply for a cheap cliffhanger, fine, then he will have developed an overly conventional plotline and in turn will deserve our ridicule. But if the story of Dick's apparent criminality is explored in an interesting and unexpected way, then we can celebrate it as yet another excellent Snyder story.
Because Criminal #4 is the final issue of an arc, we can assess the issue and the story in great depth. Conversely, because this is the first issue of a completely new DC Universe, we can assess only this issue and its story promises. So far, as far as I'm concerned, the book is interesting enough to continue reading the series. And the cliffhanger, while it follows genre conventions, does not necessarily promise a conventional storyline.
Once this Batman arc ends and we see the full story, then we'll be able to see if Snyder innovates or relies on cliche.
