I’d flip that around to say people shouldn’t seek to be a fan of a “franchise”. To be a fan of a franchise in general is to put a big sign on your back saying “I’m a sucker for whatever company owns the rights and I will spend money if you vaguely make it themed along the lines of the franchise”.
If you only like three of the movies, you’re not a fan of the franchise, you’re just a fan of three movies.
