Not an easy film.
Not easy at all.
As someone who ‘gets’ engineer speak I can follow the first half of this film perfectly, and I can understand the concepts of how the time machine in this film works. I start to lose the plot a bit once they’re using it however.
If you found the Matrix complex, this is off the scale, the film was made on a seriously small budget, but at no point does it feel like they had to throw away artistic integrity in order to make a shot. It’s a film about engineers accidentally making a time travel machine, and it feels like it was filmed by engineers.
XKCD ( a web comic ) is what pushed me in the direction of this film, as it featured an awesome graph of character interactions over time for Star Wars / LOTRs and Primer. View the graph.
What I like about the film is that the characters are totally genuine, the plot may be difficult to follow, but it is engrossing, its free to watch online with googlevideos and the website has an active forum still discussing the plot 6 years after its release.
Not the sort of film you watch when you’re in a bad mood, nor the kind of film you watch whilst doing something, miss a key frame or don’t think about what they’re doing could mean just floundering through the rest of the film.
But definitely a film you should check out, but it demands your full attention.
ps: this link explains it all. Its a bit of a brain-fuck though.
