My immediate reaction at the end was, "Wait, what . . . Oh, OK. Yeah. I get it. I want that 62 minutes back." But now, the more I think about it, the more I am smiling and coming to see it as quite delightful. Quite a few "Oh, I see what you did there" moments. There is nothing else quite like it. Any more commentary on my reactions and what triggered them would likely be spoilers.

But I will say that if you liked Primer and Upstream Color by Shane Carruth a lot, then you are more likely to accept Nestor as worth watching than if you did not like those films.

EDIT: I meant to mention that it's now included on Amazon Prime.
