DVD forums have threads on the best film DVD commentaries come up all the time, but I've never seen one that just focuses on the ones for TV DVDs. Theoretically, commentaries for TV DVDs should be better since you have less time to fill up with useless information and long pauses that plague film commentaries. Here are two examples that I like: 1. Joss Whedon on "Welcome to the Hellmouth"- Informative and entertaining. 2. All the "Futurama" commentaries- I like the ones for "The Simpsons"too, but I think these are better since "Futurama" has so much visual content and sometimes obscure jokes that need explaining.
