The studio was expecting a GOOD movie lol. Affleck had done Argo and GWH and was trying to establish himself as a serious director/writer. When WB green-lit the project they expected it to be on Argos level or what would later be the jokers level. A critically acclaimed film.share
Death stroke was going to be the main villain. He blamed Batman for the death of his son and wanted to break Batman down as revenge. He starts killing people close to Batman like Alfred trying to get Batman to understand his level of pain. He also releases many other villains in Arkham and they also attack Batman. Batman is actually driven insane and spends a lot of time in Arkham Asylum as the villains escape. He starts relating to the villains and feeling guilty about putting some of them away.
It sounded interesting but the finished script was garbage. It was BvS level. Nothing like Argo or what the studio was expecting from the people behind the movie. WB felt catfished and let the team know how unhappy they were with the script.
Affleck was not happy that it was not well received by WB and felt that the script was good enough. He felt like they were treating him like Snyder and destroying his vision for Batman. After some rewrites also were not received well, he dropped out and WB hired Reeves.
This new Batman is very good and is Oscar worthy. It’s more like Zodiac and Seven. Paul Dano plays a serial killer targeting Gotham’s elite. It’s dark and a psychological thriller. It’s more what WB was expecting with the other Batman movie.
