Here is my take if you want to cleanse yourself of Lucas's B.S. Never ever stop loving the Original SW, but toss aside everything else, including ESB & ROTJ. Now many fans here will give me crap for this theory, but here goes:

If you just love the Original SW, you don't have to think about anything about the 'saga' per say, meaning all the crap Lucas ruined with the PT, and in some ways with ROTJ, is all gone now. SW '77 is a 2 hour movie with a beginning, a middle, and a true ending, and nothing else happens after it. Princess Leia, Luke, and Darth Vader are not related, meaning the Skywalker family drama has nothing to do with anything pertaining to the movie.

By still loving The Original SW, you don't have to buy any boxset anymore, on possibly wasting your money on movies you do and don't like, in time the Original SW will pop up for sale on its own, and you buy it just like you would buy Field of Dreams or The Untouchables as they standalone itself.

I hate what Lucas has done to SW, and the fact that you have the SE, OOT, PT, and all the other bullshit that has made this series mediocre, you can always fall back on that movie in 1977, and watch it in THAT context, and that movie will always be #1 in my book.
