Primer (movie)
Primer has a confusing plot. The dialogue is difficult to understand.  Carruth decided not to make the language simpler for the audience. The movie won the Grand Jury Prize at the 2004 Sundance Film Festival. It then played in a small number of theatres in the United States. It is also available on DVD. It is now popular as a cult movie. People still talk and write about how to figure out the plot.
