Now the lots of people have netflix instant streaming checkout the movie named

primer

It is a very interesting layered movie,

Definitely not based on special fx very plot character and tech driven,

Engineers will understand it.

As will armchair scientists,

The rest should enjoy the thriller of it,

It takes more than one viewing to understand it fully. The first time I saw it I got the gist of it but on repeated screenings I now understand it much more clearly.

saw primer when it came out on dvd, classic then - still now,
