In Logan, there is a very prominent motif of returning to the past. Laura and Gabriel both had old X-Men comics, and of course the lat/lon location of the fictional Eden in the comics was used as a gathering point. The vehicles they drove regressed from the futuristic Cadillac, to a ~2000 used truck, to a beat-up old wagon from ~80s. And lastly, there's the kids cutting old Logan's beard hair to match his classic Wolverine look.
I didn't understand the purpose of this motif in the story. Can someone explain this?
