Deciding by committee what art to make never works. At best, you get a watered-down, boring version. Certainly, nothing excellent.
Rather the decision must be made by a single individual who is passionate and committed to that art.
Once decided, you can absolutely produce said art by committee. Especially in film or theatre where collaboration is necessary and vital.
However in order to succeed and thrive, each committee must be spearheaded by a single individual who is the most knowledgable and passionate about the task at hand. And, after weighing input from the committee members, that individual solely decides what, when and how the task will be carried out.
Otherwise nothing gets done. Or at least, nothing excellent.
