Aporia (2023)

Since Malcolm's accidental death, his widow Sophie and their daughter have been so overtaken by grief that when his best friend tells her of a machine that could get Malcolm back to them, it's an immediate lifeline for her and she insists they try to use it. Though this machine can't send a person back in time, it is strong enough to hit a target with a "bullet" of energy, assuming you know exactly where the target was at a certain time. Theoretically.

Even though time travel has been done dozens of times before, this story found a new idea to explore. No one goes anywhere new or repeats any days -- instead, reality itself shifts around its inhabitants. The exception to this reality shift is that the person/people in the room with the machine only remember the "original" timeline, having to play catch-up with the new reality everyone else has lived. 

Judy Greer made me feel the weight of the unintended consequences and the guilt that goes along with them. It's a real "what would I do" story and, in the end, I was so satisfied with their answer to that question.
