And were more concerned with shoving as many OT images and references into TFA as possible.
Most of the imagery wasn’t from the OT. Only the audio from Cloud City, and Obi-Wan’s line (technically, that wasn’t either. The line itself is new, and half was voiced by a reference to the
PT.)
It was mostly just Rey’s own memories, and backstory her current situation (has Luke’s map, has Luke’s lightsaber, being chased by Ren.)
This idea that a saber weapon can choose it's wielder and that it can give a person visions of places it has been, it's previous owner (cloaked) and even the voice of Obi-Wan Kenobi ("these are your first steps), is ludicrous. It's the twisting of facts to suit theories, instead of theories to suit facts.
We’re never given any indication the vision was
meant to be showing ‘who/where the lightsaber’ had been.
-It wasn’t present in the stuff pertaining to Rey herself,
-the Cloud City scene is after Luke had his hand severed and dropped it
-Kylo and the Knights of Ren had nothing to do with it
-it didn’t join Obi-Wan on his trip to the afterlife
-We don’t see it in the scene with Luke and R2.
