I'm no expert, but I'd say it depends.....

on how many videos you plan on making. If you just plan on making one video, then I'd make a promotional video. Making a lot of shorter clips describing a single episode and your opinion of it per video seems to me to be the better advertising route.

The latter strategy would lead to a greater chance of a random person seeing your product. It also could provide the opportunity to interpret future south park episodes if your current book exceeds your expectations. It's ultimately up to you and how much time you wish to spend on the videos, but your messages deserve to be seen by more people. Good luck in whichever way you decide to go.
