Donnie Darko

I am a big fan of the work of Jake Gyllenhaal and I always loved the movie Donnie Darko. I bought the cutting administration and theoretical version a while ago and I always thought I understood the film but the director's cut seemed to have made me a bit more confusing it still allowed a few questions I for the film in place. I have seen both movies several times, read about a number of things about the Internet, but many people have different explanations for this film, which confuses me even more. I was wondering if someone can give me a correct and complete explanation from the film, perhaps the beginning? Explain that the tangent and the Primary Universe, etc. so I can keep my thoughts in check and see if I have the good idea of this film. How / why the engine back in time, why Donnie later in the film sent the engine back to what looked like a single point in time he fell in his room in the first round.

Well, it's a long question. A tangent universe could be the one you live in the moment, but in your mind you think it is a primary universe, if the primary universe is one that melts in your head, you know what the hell is going on, and if you schizophrania then you have two different personalities and therefore live in two different worlds. My girlfriend could answer that question much better, but what I can say at the moment. Thus, the jet engine has not been sent Donnie drunk, he just happened to me sucked into the primary reality of reality tangent ... I do not know how to say it-a black hole? - And that's what happened. At least that's what I got out of it.
