Content films necessary don't go by the content, they go by the emotions. Content films are about content whether you want to portray the content or sell it through humour, through seriousness, is a choice of the filmmaker.
In my opinion, understanding who your target audience is, and what they want, and writing to them (and only them!) is the most important component of being successful as an author.
It's supposed to be entertainment. It's not supposed to be a documentary.
I can't titillate the audience just for the sake of doing it.
Just because I'm showing somebody being disemboweled doesn't mean that I have to get heavy and put a message behind it.
If you're not entertaining, what the hell's the point?
There are several key pieces to keeping audiences engaged, and the evolution of that. One of them, mostly importantly really, is to have a brand that has purpose and value.
Whatever content you create, let it revolve around your interests. You shouldn't create things just because you think other people want to watch it.
You have to keep your audience in your mind; if you're writing stuff that you know nobody's going to care about then you should rethink what you're doing!
We often get blinded by the forms in which content is produced, rather than the job that the content does.
