Great movie! If you want to be entertained and have a few good laughs, see this movie. The music is also very good,

When a movie has you begging for it to end not even half way through it's pure crap. We've all seen this movie and this characters millions of times, nothing new in it. Don't waste your time.

Good films always raise compelling questions, whether the format is fiction or documentary fact.

A terrific literary drama and character piece that shows how the process of creating art can be seen differently by those doing it and those looking at it from the outside.

This film is very much like a found footage, fly on the wall documentary. The characters are scientist/engineers/inventors, they are being themselves, not distracting from the story, all they are interested in is making discoveries, making money, learning. The story is about their invention and how it has an affect on them, not their social life or romance.

Most Complicated Sci Fi Movie Ever Made?? Could be ! Most realistic time travel Movie Ever Made ?? Sure is.. !This has to be one of the coolest, cleverest, and most innovative time travel movies ever made period. Forget Memento, Interstellar or Inception, this movie will screw with your mind big time! You will be confused, might have to see it twice. No actually in fact you need to watch it twice. Or more!!!!This ultra low budge movie succeed where so many time travel movie fail. Making it scientifically sound, accurate and above all it opens the Pandora box of questions such subject raises.

Pay no attention to the bad reviews they can't appreciate the uniqueness of this and for some reason I can't understand they expect this first time director and crew who mostly all have no experience to produce a big budget Hollywood production. Oh well their loss.. But let me explain why this movie is so good.First off Primer does not throw its plot in your face. You are essentially an outsider getting bits and pieces of information along the way just like the main characters.There is some technical jargon throughout the film that you don't really need to understand.. The only thing that you really need to understand is literally drawn out for you. The rest is fairly easy to infer from context. This film is directed by an engineer and this take on a time travel movie takes something that most time travel movies just kind of do whatever and don't explain the way it works. (think Flux capacitor was the only thing that back to the future said and you were just supposed to take it and run with it) primer doesn't do that. It actually gives you an explanation of why time travel in the movie works.. And it's so good that I bet some real engineers have messed with it after seeing this. That in itself is worth watching the movie.. Its brilliant. Because of the way the time travel works in this movie also helps develop the movie and the story falls into place. You as the viewer receive information at the same pace as the characters in the film and you understand things (or don't understand things) at the same rate they do. This is a very realistic movie and I could see real engineers handling this the exact same way as the main characters.Since this is a first time director you are not going to see a lot of fancy shot and there is no cgi or special effects. And it gives it a very nice overall feel of watching a documentary about the discovery of time travel but with better camera work than a documentary. Most of the lighting is all natural. There are no sets. The night scenes are night with enough lighting to see what you need but not so much that you are like "why are their two moons?"Primer is a journey into discovery. You get to enjoy the discovery with the characters and follow them through what unfolds. You will have some questions at the end but not much. There are guides out there that go into a lot of detail to really over explain the time line of the movie but you don't need it. Some information you might be looking for simply isn't in the film at all.. But if the information you are looking for wasn't known by the main characters.. You won't know it either (unless you are bold enough to watch with commentary... I never watch a movie with commentary.. Ever.. And I watched both director and crew commentary on this because I thoroughly enjoyed this movie way more than I thought I would.)Watch this movie.. Pay attention.. Listen.. And enjoy one of the best movies I have ever seen.

I don't really get those 1 star reviews stating "I'm a sci-fi / time traveling movie fan". You see, Primer is a perfect example of a movie, where the execution doesn't really matter. It's low budget, acting might seem corny to some viewers and the talking of the actors sounds like it's coming from some sort of a plastic box. But that's not the point. As we've been taught in our film class, the most important thing for a good film is an idea not the actual execution. And what a hell of an idea the creator of this one had! I've never seen a more plausible time travel movie before. The idea is so realistic, it kept me thinking until I went to sleep... and dreamed about it! Primer is maybe not fun to watch, but it did something not every movie can pull: A sort of an enablement - A need to find out what the hell happened right after the rolling credits. If there was no internet, you'd HAVE to watch the movie again. Maybe even several times to "get deeper". I have to admit I was too lazy for that and did the googling. There are bucketful of articles, videos, schemes, timelines etc. Have your other "sci-fi / time traveling movies" done the same? To enable the viewer to think and research? Or does it hurt? How's that the thinking shouldn't be a form of entertainment? Or are you simply angry you have to think? But enough of the accusations. Any form of good art should move you, enable you, change you, leave a mark in your mind and Primer have definitely done that. Not only with me, but with all the other movie buffs, who've sacrificed their time for the sake of explanation, questions, discussion. That sort of community is the best proof, that this movie deserves highest rating.
