I was batman fans and very excited to watch bvs,
But i remember yawned about 2 to 3 times watching bvs...
Mos was a good movie, it has deep conflict.
It needed a grand sequel to get general audience hooked with this new superman, but instead some years later when general audience loose their memory of mos, they were given heavy theme bvs.
Why that long to build a universe? It has lost momentum.
Then they shot JL, but they didnt expect ww to be successful and liked by critics and general audience (yes, highlight on general audience, not bvs die hard fans).
Ww created momentum again (now i'm ww fans), but JL already shot as continuance of bvs theme, there they did some adjustments and reshoots and cuts,
The result, even tho JL was suffering from critics, general audience seems to like it so there's still hope.
I think general plot and storyline still needed but (with all respect to snyder) dont take snyder's direction anymore. Build standalone movies, those who can create momentum, use them to build universe.
Currently we got wonder woman and new superman minus mustache, this two can be used to build universe in the long run.
