Its being said that talks have not been broken down as reported, but taking a break before reaching an agreement. The reason for this is not because of Reeves, WB, creative control, or anything; apparently, it's being said the reason for the talks coming to a halt is because of Reeves' agent being a hardball in trying to get more money for Reeves' paycheck. 
I doubt WB would give Reeves a paycheck that wouldn't reflect this man's work, or was less than desirable. But if this is true, the agent is trying to take advantage of WB in trying to get more money, which...okay, it could work; but depending on the amount, if the news this is any indication, it might kill Reeves' chance to direct the movie. That is, if WB will do anything to get him, or will go down the list. 
In the end, WB will make The Batman, no matter what.
I do have a question though: what kind of Batman movie is this? Given the news reports here and here, I'd assume Affleck/Johns turned in a script that needed an extra punch, which was delivered by Terrio. But in the end, what Batman movie is this? I ask because, WB is very reactionary post-BvS, and want to do whatever it takes to please everybody, and Batman lives in a superhero universe unlike Nolan's Dark Knight trilogy. A superhero Batman? Last time that happened was Batman Forever. Is that what WB wants? Or am I going nuts?
