I'm bored to tears with "evil counterparts", especially when most of these characters already have an evil counterpart of themselves in their regular rogues' gallery. Zoom already is evil Flash. Sinestro already is evil Green Lantern. Superman already has Cyborg Superman and Bizarro and General Zod (and probably a half-dozen others that no one remembers). The only difference is these characters (with the exception of Bizarro perhaps) all have an actual backstory that explains why they aren't just carbon copies of the hero with extra toner. They are "evil" for a reason other than they just come from a Star Trek-style parallel universe where everyone is evil. It's the laziest kind of time-filler juvenile 10-year-old on a playground sort of storytelling imaginable.
That was acceptable in the doldrums of the Silver Age, but we should be better than that now.
