In My Room (2018)

Nothing happens in this German ??. Overview: Somehow, and ridiculously not explained, everyone disappears (like totally vanished) except our central male character &, you guessed it, someone else shows up. Dumb! Sequence of events: Start w/our camera view jumping all over the place; dark disco w/flashing lights; cig. smoking; walking bicycle; driving car; aged dying grandma; more cig. smoking w/breakfast; more driving; abandoned vehicles on roads; more driving; more walking; starts farming (why w/abandoned stores?); unlikely other (with all the right physical attributes) shows up at his desolate farm; the end. If there's some underlying message about, who knows, humanity it got buried in the presentation.
