That idea is still less ridiculous than tracking ships in lightspeed? Would distance not be a factor or at least touch on how its possible?. "oh it just is" Why not just make it a traitor or a bug on the ship that would be more plausiable. Speechless how lazy and silly the creative team behind this, just take any of the fan/book material out there in the last 30 years and it would be miles better than this unoriginal, unsophisticated, drivel. Imo it doesnt even fit into star wars mythos at all.
If they wanted to reset everything as a few already suggested make it in the future and instead of just ending the jedi and sith with no explaination, make a more powerful antagonistthat to wipe them out.
This trailer has a more compelling story and intrigue than the 2 films put together and its only 4mins long. this is what star wars should have been like.
