The ending of Night Moves came a little abrupt to me. After killing Dena somewhat "accidentally" Josh ends up somewhere in California and casually applies for a job at an outdoor shop, apparently trying to go under the radar. However, when he's about to fill the application form at the clerk's desk, he looks into a ceiling mirror which shows the shop area with a few customers and that's where the film ends.
I don't quite know what to make of this ending. I could get behind Josh's future being left deliberately vague and that might be somewhat fitting to the rest of the film's unagitated yet ominous atmosphere, but at the same time him looking into that mirror made me wonder if anything significant happened there. Did he actually see something in that mirror (did he maybe even imagine Dena)? Are we the audience supposed to see something there too?
Even after the second watch I'm still not sure what to make of the ending or if I maybe even missed something significant. Or maybe it's just the abruptness and plainness of the ending that confuses me. Can anyone shed a little more light on how the very ending of the film figures into the rest of the story and what it could be trying to tell us or even just what exactly happened there?
