Woah. If this were a Christopher Nolan movie....that's a parlour game I can get behind.
First, remove character names unless they are absolutely demanded by the story. Batman? Whose that?
Second, take any situation and make it crazily complex but leave giant narrative holes that you fix with "spinning newspaper" level solutions or with camera cuts in which you are to assume that everything ended up fine.
Third, expect people to fall for story devices as tired as "she had three psychiatrists declare her sane before she committed suicide and blamed me for her murder"
Fourth, use your gravitas as a director to hire actors so talented that it fixes a lot of the top three problems.
I love me some Christopher Nolan but the problems with Christopher Nolan movies can be a lot of fun to unpack.
