Absolutely ingenious
It’s a slow burn at first, but by the middle I had an irrepressible grin on my face. I would actually urge anyone interested in time travel to take my word for it and go watch it without reading any further, because a big part of the fun was not seeing where it was going.
But I just have to say for the record that I’m so impressed by the way they incorporated the changing time stream within the documentary. My ten-year-old daughter really enjoys time travel stories, but I would not be able to show this to her – she would be way too confused. Unlike any other time travel movie or story I can think of, there is no POV character who keep straight what has happened and how things have changed.
The talking heads experts being interviewed in this fake documentary format clearly don’t realize how their subject has changed, so it all has to be picked up by inference. That the filmmakers trust the audience to figure it all out, and leave just enough evidence for them to do so if they are paying attention, is a marvel of clockwork construction.
2014 turns out to be a great year for time travel movies. This and "Predestination" are actually my two favorites, hidden gems I only learned about recently. But then there were also two big Hollywood productions that were also really good: "Edge of Tomorrow" and "X-Men: Days of Future Past".
