Um, okay... I haven't really looked much into either Homer or Shakespeare, but come on, seriously? The works of those guys are revered first and foremost for their POETRY, and their mastery over language.
How does Star Wars with its "witty dialogue" and "cool, memorable one-liners" even COMPETE? Look at the dialogue between Vader and Luke in ESB - what delivers it is really the DELIVERY, the dialog itself is pretty much a cliché combat of relatively uninspired, derivative one-liners. Then look at those poems you cite, the lengthy monologues and verbal clashes, and tell me there is ANY comparison.
It's like saying that 50 years from now, we'll look at Metallica or Radiohead as "the new Bach" or something - just pure nonsense.
Saying that the "stories" of both are silly, is really just a lazy cop-out. OF COURSE they're silly. That's not the point.
