So the DCEU is now officially called...
Worlds of DC
^^^
They have to, considering they're doing a 'not in DCEU continuity' "Joker" stand alone film. If that film works, you can expect more of those types of DC comic book film projects from DC. Unlike Marvel Studios, which DID have some box office underperformers; but did let it alter their ultimate MCU plans, and it worked out well for them...Warner Brothers is all about the bottom line; and when their Justice League film (the most expensive in the DCEU series to make) brought in the lowest box office total of the DCEU - WB is scrambling on how to turn their DC comics properties around to be profitable.
'DCEU' is a damaged tagline (and even in what should be 'built in' interest, many people (including in my circle of friends) - "Oh it's a DCEU film eh? I'll wait for it to show on HBO..."
For my part, I thought "Man of Steel" was okay (and on par with MCU films like "Iron Man 2" and "The Incredible Hulk"); thought BvS was disappointing (Lex Luthor came across more like a version of 'The Joker' and I disliked that; plus with the actions Superman took/the way he was perceived in that world, the funeral and world reaction to his death made no sense. It was like Snyder gave his version of Superman the funeral the DC comics version of Supes would get); Suicide Squad was just plan crap (although Margo Robbie worked for me as Harley Quinn and Wonder Woman in BvS was great). Wonder Woman was probably the DCEU's best film overall, but it had some issues that didn't put it up there for me alongside some of the MCU's best like say "Captain America: Winter Soldier".
Again, I liked Justice League overall (for me the Cyborg character was well done); but "Steppenwolf" just came across as you standard mustache twirling villain and was a disappointment when for me everything in BvS screamed "Darksied is coming..."

And yes, mustache twirling Villians can work and be fine for smaller stand alone stories, but (IMO) not for you big/blockbuster "Let's get the full team together..." 'epic' style film.
Hell, if they had Darkseid step through at the end of JL, that would have caught my interest and made me want to see a JL II; but WB being the not really wanting to take a chance/commit to something major gave us the "Oh look it's the 'Legion of Doom'..." which was honestly a big 'meh' for me. (YMMV).
So, yeah, at this point WB wants to try and get a version of their DC comics characters that nets them box office like the three MCU Avengers films; and they're unwilling to take the long term risk of trying to publicly reinvigorate the DCEU's image, so they now have a new
Worlds of DC movie brand (Which probably won't sway the built in audience, but may grab back general audiences.)
