Here is a little video I made as a final project for my Theatre History class
While this video is by no means a replacement for actually reading Poetics, I hope it helps to simplify it since I know all you students have a lot of reading to do ;)
UPDATE Jan 24 2016: Does that say 6700+ views?? Holy cow! I had no idea anyone other than my prof would ever watch this... but here we are. I'm so glad to see it has helped some of you out :) Thanks so much for watching this and taking the time to comment. Definitely made the 15+ hours of work on this worthwhile!
