EDIT: I personally think the vision/glimpses would need to be on the more subtle side, if we did it.
Subtlety? In a J.J. Abrams film?
But in all seriousness, I don’t think a subtle vision would jive within an Abrams film. He’s all about that big action, frenetic camera work, and chaotic sequences. And his vision sequences especially are such violent affairs. Look at Kirk’s Mind Meld in Star Trek (2009). Or Rey’s Sith Throne Vision.
I think a great comparison is Rey’s visions in The Force Awakens vs. The Last Jedi. Rian Johnson came up with this quiet, eerie, mysterious sequence dripping with symbolism. J.J.’s scene involves eight scene changes, assassinations, rotating corridors, burning buildings, screaming children being sold into slavery…
Not to say that one is good and one is bad, just that I’d be worried about how well a “subtle” vision would fit with the rest of J.J.’s style.
