Spike Lee the director of Blackkklansman. States that you can’t make a movie on a cultural issue if you are not part of the culture yourself.
In my opinion I think this depends on the movie your making. An example of what I mean come from the 2 movies he has criticised. Detroit and Django Unchained.
An example of the lack of experience with a cultural issue causing issues with a movie is Detroit. The focus on Detroit is the riot in Detroit. However, the overall problem with the movie is that it focusses of Detroit is showing how bad the riots were without much narrative of characterising surrounding it. This makes the message its trying to portray feel forced because of the lack of a connection the audience has to the character going through this situation.
However I think Django Unchained is an example of a movie that covers a cultural issue well by making the slavery and racism in the movie not the main focus. In making the movie focus on the character of Django and his narrative of getting back his wife shows the issues of racism and how it negatively affected Django a character the audience cares about. Showing them the importance of treating everyone with respect, without feeling forced.
