The lack of an episode number is only meaningful to me in terms of the original film. It was originally intended to be a singular work and I kind of like that. Otherwise, my concern over the notion of different episodes ends with the original trilogy. I don't care what numbers are attached since those three films are the only special films. If they want to make some new films with new numbers they can go right ahead. They can start using decimals (like 1.5 or 2.7689) and I won't give a shit since I'm probably not going to watch them.
