They did a good job with the gradual changes, but I couldn’t watch it all the way through. The main cast is just too irritating to watch. If I wanted to watch (the equivalent of) children deal with an interesting premise in adult bodies, I would just go back to Big or 13 Going On 30.
I think you have it backwards. They remember their timeline, which doesn’t match the knowledge that everyone else around them has. A quick example is
the short story The Sound of Thunder.
Maybe it’s just me, but libertarians have always been a weird bunch, because there are some large gaps between those who fall under its banner. I’ve seen anarchist commune types as well as the ‘government better watch out because I’m the only owner of THIS land’ prickly sorts at the same event. It’s not so much that the ideals of libertarian thought have been taken into conservative realms, but that the sorts of libertarians who could align with the ‘conservative’ drive to make the government small and speak up loudly are now getting their moment in the spotlight.
Your idea of it is a hilarious (sort of) possible backstory to all of the thriller/horror movies where one person is ‘the only one who remembers X!’
