No...think it will matter?
Yeah, it'll matter, most likely. At least see the original trilogy to get a sense of what Anakin's about to turn into. Not to mention they're good films (for the most part).
Well yeah I kinda do. I think GL does too. GL has publicly stated he doesn't feel its age appropriate for those under 11 or 12 irregardless if they've seen any of the other SW movies.
