True to an extent. But why would you want to create (e.g.) a movie if you don't think watching movies is worthwhile in and of itself? You're putting effort into creating something that you don't think is truly valuable. To a person with this mindset, the desire to create is cynical—they're only making movies in pursuit of extrinsic rewards such as money, fame, or success. If watching movies is thin to them, then making movies is also thin.

Conversely, an authentic filmmaker is someone who values movies in and of themselves; therefore, the authentic desire to create a movie must be downstream of a passion for watching movies. I don't think you'll find many artistically inclined filmmakers who would denigrate the act of watching movies as "thin." It's the thickness they feel in the experience of watching movies which inspired them to devote themselves to making movies in the first place.
