^ It's not just about ignoring plot-important details; it's about the entire approach, from narrative to design to shot structure. Episodes 1-6 are all thematic "mirrors" of each other and have narrative and structural elements that are heavily rooted in mythology and archetype, whereas The Force Awakens' characters are standard "copycat" characters whose only real narrative purpose is to rehash superficial characteristics present in the characters of Han, Luke, and Leia as they existed in ANH, but without any of the archetypal and mythological nuances that were infused into them by Lucas.
If you actually peel away the base levels of characterization for Rey, Finn, Poe, Kylo Ren, Maz, Snoke, Hux, Phasma, Han, and Leia, there's not actually much of any substance there for anyone other than Kylo.
Rey's appeal comes primarily from this false sense that there's some huge plot-changing secret about her lineage that's been hidden and is going to be revealed in subsequent films (something that we now know isn't actually going to be the case), Poe is a less interesting attempt to rehash Han's "charming rogue" character, Finn's just a comedy sidekick, Snoke, Maz, and Phasma are basically there to provide exposition and/or "look cool", But is your generic "bad guy military officer", and Han and Leia are essentially stuck in the same roles they occupied in the OT, albeit as older characters, although Han does end up becoming the film's "Obi-Wan" as the mentor figure who sacrifices themselves for the hero(ine).
