The OT relies on itself to build its story, so it should be seen first at all costs. The sequels, and even Rogue One, rely on the OT to continue that story and work as well as they do. For that reason, I don’t think it’s important for the sequel trilogy not to spoil any OT twists, it’s a continuation of that story, the revelations have already been made. I want to know how these characters deal with those revelations, heck they can even be made new again to the new characters. I don’t think it’s important to maintain any mystery revealed in the OT. The prequels, on the other hand, are another story.
I agree more or less. It’d be hard to continue the Skywalker storyline in the ST without talking about the reveals made in the OT.
