Because my whole focus in Episode III will be to enjoy the eagerly anticipated and spectacularly brilliant acting by Hayden Christensen as Aniken Skywalker/Darth Vader, I'm not sure your pre-movie consumption would suit me. I want to perfectly alert and ready to swoon at his pithy lines and faultless delivery. I could still take advantage of the snack line diversion method for creating seat availability though, that is certaily workable. It sounds as though your suggestion is to go ahead and see the movie and wait on the watch.
I have kid issues and I am not in a big hurry to see this movie...or any other for that matter. It is likely I will wait a couple months for it to come out on DVD. For some things I have a great deal of patience...seeing movies is one of those things for which Job had nothing on me.
