It was riddled in the past with personal rivalry, big ego's, envy etc by the people who ran DC, with the characters caught in the middle. Now many of those people are gone, you got people who don't love the characters but use them for personal agendas or not having an idea how to make them work. Bat provides a comfort zone, so who cares at the end of the day you still get paid.
Lack of talent at DC is now very evident and mostly they are not into these characters, which is sad.
