i am invested, i care about the author, the medium, and the subjectmatter. the laziness this project was slapped together with is an obstacle for me and others to learn or experience anything salient buried in there, and since the guy has had good things to say in the past, it's a disappointment.
but your dismissive attitude crops up every time people are talking about media length, either 'skill issue' or 'i don't really care, why do you care?'. what you did to experience that video was work. you organized & played it how you liked, at a pace that worked for you. but folks don't want to work to see something, and your assumption that your methods would work for all is incorrect. how long can these intermissions be? will somebody forget important details? how independent is each 'chapter', can they stand on their own? when the author wrestles these, they can organize the work to support intended pauses---when the audience does it they're rolling a dice. i can pause in the middle of any movie, technically, and possibly come back remembering perfectly, or not. but an intermission that was made with intention re-establishes and information on either end are organized with it in mind.
