Primer - Good Time Travel Movie

Primer is a movie in which I couldn't understand pretty much anything the characters were talking about, they could have been speaking in another language.  I couldn't really understand the chronology of the plot.  Basically, in general, I couldn't understand much of anything that was going on in the movie.  But, I loved it.  And, I keep thinking about it.  If you like short, brain-teaser movies, this is one for you.

And, after you're done, here are info-graphics for you:
