Well, since it certainly seems open to debate, i thought a thread for the discussion of the white halls from a story perspective would be nice.
Personally i believe the white halls we now have access too are not, and were intended to be, the same white hallway system the movie characters had access to.
That hall provided direct access to innumerable different places/locations, as far as we know, inside the simulation.
While these halls contain rooms which download/upload the person's data to different locations, as far as we know, outside the simulation.
I think it's perfectly feasible that two different white hall systems would've been needed for the difference in inter-system movement and outer-system movement.
You thoughts?
