I agree that there is no wrong or right in this context. I do however fear that if we are unable to concentrate on media for longer periods of time, the "depth" of the media will diminish.

You engage in a real emotional thought process, following along with the main character, hoping with them, fearing with them. Short media doesn't have that kind of engagement.
