Rick Geary’s biography of Trotsky isn’t terrible. Trotsky: A Graphic Biography lays out the facts about Trotsky’s life and politics in a mostly coherent way. It just didn’t really need to be a comic. The images tended not to really add anything or show anything that wasn’t going on in the essay dwelling in the captions.
This isn’t to say I didn’t learn anything from it. It was a good Coles Notes kind of document, but it’s nowhere near as good as Logicomix or Suspended in Language which made much better use of the comix form.
