-Those old enough to remember Star Wars as a stand-alone film.
-Those who grew up with the trilogy as a complete set.
-Those who grew up with the Special Edition and prequels.
For the first group, even the second two films were an intrusion of sorts. This is my father - he still insists that "Darth" is Vader's first name.
I'm in the second group. Han shoots first, damnit, but I don't flinch at the title "A New Hope," and I'm happy to tell you why a planet of Ewoks is better than a planet of Wookies.
As for the third group, that's my brothers, but I'm not sure there is much consensus opinion, apart from "Natalie Portman is hot." I defer to bkev et all.
Oh, and I'm 26.
