As for the other part, you seem to be implying that I am young, and therefore blind to the PTs 'rampant' nostalgia or something. But when looked at in detail, the nostalgia is often subverted, like the inverse structure of AOTC and EBS being used to show the descent of the Republic. And there's so much new stuff, the central plot of ROTS doesn't really map to any previous film, while TFA's is almost word-for-word ANH's. X-wings and TIE fighters isn't just the visual style though, it's also the kind of story that can be told. With an identical Rebels Vs. Empire conflict, TFA might as well be set during the OT, than 30 years later. The PT, for better or worse, tells different kinds of stories. Time will tell whether TLJ can be something new and interesting, but it still has to work with only what was set up in ANH, because TFA didn't have anything from the other films, or show any progression. That also hurts one of the central parts of TFA. Rey is literally digging around in the bones of the OT. That's a good image, showing it dead and buried, with Kylo stuck in rut of nostalgia for Vader too. But it doesn't work when both forces are identical to the ships buried at Jakku. That makes the central message of damaging nostalgia hypocritical, and renders TFA's most interesting central theme pointless.
