I'm not as "radical" as I sound. Star Wars may be a simple series of films of "space wizards" and adventure, but they are more than what you make them out to be as well. The original films are cultural touchstones. Amazing classics in American cinema. Have they not inspired countless people? Is the OT not representative of long standing culturally induced elements of American culture? Doesn't the "Evil Empire" and its regression from the great Old Republic just ring of the disillusionment Americans generally felt with their government in the late 70s? Isn't it notable as being America's modern "fairy tale" and myth? I can't see how it isn't of that regard. I definitely did hyperbolize and make some faulty analogies by comparing them to the mythic works of Ancient Greece and Rome, which were accepted as religious dogma and were much more universally read and accepted in their respective societies and eras. However, one cannot underestimate the influence, impact, and sheer meaning of the Star Wars Trilogy, and honestly, I kind of find your dismissal to be slightly disturbing!
Anyway, what you said about Star Trek is totally different. Star Trek: The Original Series has not been re-evaluated or re-assessed in any major ways against it's original continuity or meaning. People don't retroactively call the female officers, such as Uhura, of TOS "Sir" as the Rick Berman era shows will address the female officers. No current sources do this. The only thing really close to a ret-con with Star Trek is the whole "Trouble with Klingons" and the retroactive explanation given as to the changed appearance in Enterprise. Also the later Trek shows, besides TNG and DS9, have in no way, shape, or form entered pop culture in any major degree, and despite its' former great success, DS9 rarely finds itself parodied or mentioned on Family Guy or South Park, for example. Also, Star Trek, (not counting the more recent "remastering") hasn't seen any major changes against it, and even the new (amazing) Blu-Ray sets include BOTH the original broadcast and CGI remastered versions of each episode...both in VERY high quality...and with the mono mix. Viacom/Paramount. etc is in no way keeping the original purity of the original Star Trek away from the public. Heck. The versions up on Hulu and the franchise's official website are of the original versions! In other words...it's not the same thing. Voyager and any later lackluster shows don't change the old ways. Things aren't canonically explained by being caused by the Borg or the Q (The Squire of Gothos won't even officially be said to be a Q), so the Gene Roddenberry and Gene Coon era of Star Trek remains almost entirely separate from the Rick Berman and JJ Abrams eras of Trek.
Lucas "prequelizes" the originals seemingly as much as possible with each chance he gets. Characters are now spoken of in their prequel names more than not ("Darth Sidious" rather than The Emperor), prequel plot devices are frequently in discussion with respect to the originals, and of course so much of the original films are changed beyond recognition.
I don't want a huge idealistic crusade, but I do want something to be done to preserve these beloved films and to not have to deal with all the mediocre prequel crap now drowning out the integrity of the originals.
