To me Batman v Robin was more Born to Kill than Court of Owls. Talon was Nobody. The story beats and conflicts are Born to kill.
I think the movies mixed and matched and fans missed or ignored that. fans labelled the universe new 52 due to War and the JL uniforms without stopping to actually look at the source material.
Fans saw the COO and called the movie an adaptation of COO when the main story being told was clearly from another comic.
As someone who got into DC and Comics thanks to Son of Batman I have to say that reading Batman and Son I found that Damian difficult to like.
I had no frame of reference going into these movies so my POV is very different.
