This situation of "lets give Snyder 70 millions so that he can create a mini series out of his JL cut and then say that nothing is going to follow it" is very weird to me. Especially considering that studios usually like to project confidence and announce that they are going to do sequels and maybe even entire universe out of the upcoming movie. Yet here, before this even gets released (does it even have a launch date yet?) they announce that it is a street that leads nowhere. To me it just doesn't add up so I got two theories:
1. As we know things are bad at ATT so maybe plans are changing every couple of months and people who thought that Snyder cut was a good idea changed their mind despite no new data being available.
2. WB likes "release the Snyder cut" community and doesn't want it to fade away so they are adding more wood to the fire. Won't surprise me if at some point Snyder will talk about how Snyder Cut was not going to happen, but fans made it happen. So you know, keep "fighting" and maybe you'll make Snyderverse happen.
