Netflix has been criticized for not having enough enduring franchises like Marvel and Star Wars. Having those would certainly aid its efforts to expand into merchandise licensing, which is one of Walt Disney Co.’s highest-margin businesses. Still, while those franchises may have helped Disney+ get a lot subscribers out of the gate, its narrow focus could also limit the ultimate size of its subscriber base. Even for viewers who favor a specific genre, the overwhelming majority of their viewing time is spent on services with broad menus, according to a recent Parks Associates survey.
