Don't do this

A talk I went to several years ago.  I'm changing details or being vague so as not to identify anything about who it was.

A power point presentation in a very boring visual style, with mostly all text, that the person read out loud or explained. So the audience saw the words, read them in a few seconds, and then had them more sloooowly explained.  The talk went on and on, for about 75 minutes. It was all in abstractions until the end, an example of one film at the very end, with a plot summary for those of us unfamiliar with it. The bulk of the talk was explicitly framed as "digressions." But then, digressions from what?

There was information and opinions, but not a coherent argument running through it, or a thesis. One slide would be "so and so says this."  We would get four bullet points about that.

There was no elegance of style or expression, no effort to put words together in a rhetorically convincing way.  No humor.

The person privileged literature by beginning and ending with it, and somehow seeing it as the ultimate horizon, but then we never got to hear about any literary works, not a single name of a novelist or poet.  It's fine not to talk about literature, but why set up the expectation that you will?
