The documentary does much more than discuss "Achtung Baby". It also runs over the band's origins, their relationship with each other (tight knit) and previous albums in particular "Joshua Tree".
It may owe something to Asimov but the screenplay is very strong. If we got the chance how many of us would behave any differently to the vacationers? I think Crichton may have struggled to find an ending as this one wasn't as strong as what went before.
