Well…this is a bender. I love ‘hard’ sci-fi, and Primer belongs very much in that tradition. This is a engrossingly fascinating absurd puzzle-box of a film. Attempting to keep up with what’s happening is half of the fun, the other half being pretending to know what’s happening. And all this in a film that’s only 77 minutes long and made with $7000. Not a single shot is wasted, not a single moment gratuitous. And of course, the science geek stuff is probably all complete claptrap, but I loved it anyway. This is a satisfyingly fun intelligent sci-fi film.
