"The movie delights me with its cocky confidence that the audience can keep up. Primer is a film for nerds, geeks, brainiacs, Academic Decathlon winners, programmers, philosophers and the kinds of people who have made it this far into the review. It will surely be hated by those who 'go to the movies to be entertained', and embraced and debated by others, who will find it entertains the parts the others do not reach."
