They wanted to skip to "their Avengers", without doing the five lead up films the MCU did before Avengers to great effect.
That's failure number one.
Number two is that grimdark is stupid, especially with DC characters. I would have gone the exact opposite direction. I would have set the entire thing as basically a period piece.
"Superman", the first movie, would have taken place in 1938. It would star an inexperienced Superman, much like his Golden Age version. I would go for plenty of black and white scenes and a Flash Gordon type feel for anything Krypton.
"Batman", the second movie, would have taken place in 1941 (before the US entry into World War II) starring Batman at the very start of his career too.
Wonder Woman, the third movie, I would have kept broadly the same and kept it in World War I.
Trinity, the fourth movie, would take place in 1955. Batman and Superman would be much more experienced now and Superman the greatest hero in the world, though never having encountered each other. The return of Wonder Woman brings them together. Their shared adventure would end with the discovery of Martian Manhunter and the threat of "the Conquerors", a parasitic race that destroyed Mars millennia ago.
The Flash, the Fifth movie, would take place in 1956, and would hook firmly into the emerging plot of the "Conquerors".
The sixth movie, the "Justice League of America" (or just "Justice League" internationally), would take place in 1960. It would introduce Hal Jordan, the Green Lantern, and bring the Conquerors (and the continent sized Starro) to Earth to do to it what they did to mars. The plot would kind of be a mixture of the amazing Justice League DCAU pilot and Darwyne Cooke's New Frontier.
Thematically, visually and stylistically, it would be more "New Frontier" than anything else.
One reason I like this is because it treats Superman as the "first" public superhero and kind of the most senior, with Batman not far behind and Wonder Woman kind of around them. The Silver Age heroes arrive when the trinity are at the height of their abilities.

DC has had Superman movies they can't really top with the two Richard Donner Films, and a "modern" take on Batman that they can't top with the Dark Knight trilogy. The only real way forward is to not compete with what they've already done.
Man of Steel falls far short of pretty much every Superman attempt to date. And the DCEU Batman... well... it does some things right (the costume, that amazing fight scene in the warehouse), but is still just... off.
The route is just to go completely different, and I think that says "period piece".
The other way to do it is end up with what Marvel began to do with the original Avengers. Over time, people got used to the idea of "Movie Thor" and "Movie Capt", that they didn't need Captain America, Thor, Iron Man, or the Hulk or anyone else being 1:1 with their comics or "idealized" versions. Civil War and Ragnarok just hit people in the face with it - Capt didn't need his shield to be Capt, and Thor didn't need his hammer. And Iron Man? Well, Robert Downey Jr. stopped playing Tony Stark after Iron Man 2, and pretty much just been playing "Robert Downey Jr" ever since, and the characters gotten better for it.
