by Walter Chaw Titled after a word meaning "irresolvable internal contradiction," Aporia is a tragicomedy of errors à la The Butterfly Effect in which three well-meaning suburbanites figure out a way to change the past but can't quite figure out how to avoid causing unexpected temporal fuckups in addition to the ones they're trying to cause. For what it's worth, their always remembering their former timelines isn't addressed in any meaningful way--nor, I guess, does it need to be, given that this is soft sci-fi and not Primer, but I did think about it. I also thought about how the title is probably fair warning against trying to Neil deGrasse Tyson the thing, and so: fair enough. What happens is that grieving widow Sophie (Judy Greer), seven months out from losing husband Malcolm (Edi Gathegi) to a drunk driver, does her best to manage the trauma she and her daughter Riley (Gaithe Herman) are going through, but it's a losing battle. She confides in her friend Jabir (Payman Maadi) that things are spiralling, and Jabir tells Sophie that he and Malcolm had been working on a time-travel device that could fire a burst of energy to a specific time and place in the past. If they were to kill the drunk driver, they figure, maybe all would be well again in their world. So they do it, and at first it seems like this Monkey's Paw is one of the rare benevolent Monkey's Paws. But then Sophie starts feeling guilty over the financial plight the drunk driver's wife, Kara (Whitney Morgan Cox), suffers in the absence of her lout of a husband.
