Could anyone please define this? Proponents of time travel always use the "done properly" argument, but often never give any clarity on how it could be "done properly"
Organic and necessary to the plotline where the time travel gives layers of meaning to not just this film but other things as well. Much as it served say Babylon 5 in "War Without End" (great model for timetravel) or "First Contact" or "The Voyage Home" - those are examples of doing it properly.
