Get a spare 30 minutes and WATCH THIS:

 All these clips are entertaining, I recommend THIS ONE ABOVE in particular to this course subject; it highlights why episode 3 in particular of the Star Wars prequels does not work- in this clip's case, it discusses the central protagonist to the story, and the storyboarding/shot selections in the film. Insightful, hilarious, it is strongly recommended you listen/watch this. (Thanks for the find, Andi :D)

 It basically boils down to a discussion on the three things I mentioned yesterday that you must try to achieve when telling a story in film, animation or comic book:
 CLARITY, EMPATHY and ENTERTAINMENT.

Original link, and the other two parts are here. All extremely funny, and trust me, you don't have to be a Star Wars fan at all to get what it's saying.
