  1. 100
    Primer unites physics and metaphysics in an ingenious guerrilla reinvention of cinematic science fiction.
  2. Consider Primer a successful lab experiment with, as they might say in techie chat rooms, significant indie-cred applications, IMHO. Oh, and :-).
  3. 90
    A half-baked conspiracy subplot in the last third makes Carruth's knotty narrative even harder to follow, but this is still scary, puzzling, and different.
  4. 88
    It is maddening, fascinating and completely successful.
  5. An ingenious blend of sci-fi and mystery.

    Refusing to dumb down for a mass market, Primer is "Mullholland Dr." for math geeks, "Memento" for mad geniuses, or simply one of the most inventive films ever made for pennies on the Hollywood dollar.

    A minor miracle of a film, this movie manages to pull off everything a major motion picture should have (great scripting, amazing acting, drama, etc.) with a mere budget of ~$7,000. It's simultaneously captivating, confusing, frustrating, and in the end, completely gratifying - even if you can't put all the pieces together on the first viewing. I already can't wait to watch it again. Full Review »

    I usually pay attention to details while watching a movie and am able to conclude the story at the end, but Primer is impossibly hard to follow. I could figure out what was going on only after reading a huge explanation article. The story is really complex as it is based on time travels, but I repeat myself, you probably won't dig it if you just watch the movie once. The other problem is Primer is really boring, most of the time nothing happens, the characters seem to take their discovery pretty casually. I respect that most of the work was made by one man, but still it could be much better. Full Review »

    In today’s day and age, we throw around the phrase “mind-blowing” a lot ( probably published three articles this morning that contain the phrase…the other articles are insinuating that you don’t know anything). However, I have to say that “Primer” is as close to a real life instance of my mind actually exploding! The way this film handled time travel came off frighteningly realistic and, if it wasn’t for the below average acting, you could easily think it was a documentary on the discovery of time travel. Even though the acting isn’t great, the film delivers an incredibly intelligent script that actually challenges the viewer and is, quite possibly, the smartest, most realistic, science fiction film I have ever seen.
