That's different from the original movies how?
I'm dead serious. Lucas used the monomyth as a template in the same way episode 7 uses episode 4. Heck, Lucas wasn't even clever enough to use some of the elements of the universal hero's journey as metaphors, everything is depressingly literal and by-the-numbers. The dialog is atrocious and the script is full of plot holes, but you overlook all of that because the action and pacing are well done, and the use of the monomyth virtually guarantees it will pull at your heart-strings as long as you can turn your brain off and go with the ride. Add to that the derring-do feel of the old Buck Rogers serials and liberal theft of the works of Kurosawa, add space ships and laser-swords and voi la! Star Wars!
Even when you downplay the creative work behind the OT, it is still orders of magnitude more creativity than Abrams' effort: merely using the original trilogy as a template.
