Borrowing elements from a wide variety of sources and blending them to create something no one has seen before is very different from creating a near carbon copy of an earlier film in the very same franchise.
As far as my ratings go, I pretty much agree with ZkinandBonez. I really enjoy Star Wars, but even ESB is an 8 or 8.5 in a world full of amazing films. That’s why I give TFA a 5 or 6 tops.
