Before each episode of the prequels came out, I would watch all of the movies I had just prior to seeing the new film in the theater. Now that all the films are out, I tend to just sit down and watch particular scenes. I find am more inclined to watch the OOT all the way through than I am the prequels, though. But these days, with the random access of DVDs, I often just watch certain portions of all the films... and the Holiday Special.
