I love TLZ too and broke my bank buying it on Blu-ray. In my top 10 shows of all time for sure.
I think stories of TLZ are so special that the science element is a non-factor.
In 'Where is Everybody' it matters not that he is actually in a simulator--what matters is the 24 minutes before that and his plight as a lonely confused human being.
Of course the quality of the fiction is paramount--I'm just playing devil's advocate.
