Yes. I don't think they need to go quite as far as they have, but absolutely.
Variety is good - and for as much as I will always deride the DCEU for what (imo) it royally screwed up, there was real potential for some solid gravitas in there. If it could have been less wallow-y and had more active (in the narrative sense, not the standard meaning) protagonists along with a bit more power fantasy in there, I think they would have had something better than what the MCU brought to the table - certainly more unique.
The problem for WB now is that they've had the "dark" rep stick hard enough that they almost have to overdo the opposite just to knock the calcified opinion off of their name - which, while unfortunate, is entirely of their own making.
