One of the great things about DVDs is that companies are really starting to put together collections of movies and shows in one box, usually with commentaries. Mine are probably the Simpsons seasons, because the commentaries are great and hey, how can you go wrong with the Simpsons? Also at the top of the list are the Futurama set and the MST3K collections. I'd put the Family Guy collection as one of the best because the episodes are so good, but the commentaries are few and not very good. My list of ones I still want would be the Nightmare on Elm Street, South Park, and Monty Python Complete Episode collections.
