Oh boy. Not enough people liked MOS, so they twisted that world's continuity and forced Batman into it. Even fewer people liked BvS (by the way, did they ever explained why it wasn't just "versus"???), so they forced a new direction, and ultimately a new director, into JL (which was terrible anyway).
Now Zack Snyder is basically forcing his own narrative to accommodate fan theories. The Snyderverse must be the only narrative universe which is so awfully flawed that they keep course-correcting it even after it is dead and buried.
