And yet, the long form exists. Because reading (or in the case of the Odyssey, narrating/speaking the story) is experiential. Just as you can summarize a movie, the plot is very little of the point of WHY you would watch something. It might help you discuss elements of it, or determine if it sounds remotely interesting to you, but we experience art because it is, despite appearances, a succinct way of transmitting complex ideas and experiences.
