What Movies Should be a Mini Series?

What movies do you think would benefit from being expanded into a mini series, instead of a full length features? I thought of this question when I saw a post about shorter movies, where someone mentioned the new Batman. What are r/movies thoughts?

I think Interstellar may have benefited from this. It's a long movie already, and could have been broken into a section on earth, some of the areas in space and so on.
