Night Sky has an intriguing premise—underground, an elderly couple visits a portal to another world, while aboveground they go through the trials and tribulations of marriage and old age. You would think that the sci-fi element would overpower everything else in this story, but on the contrary, it’s the slice-of-life chemistry between Franklin and Irene York (played by Oscar winners JK Simmons and Sissy Spacek, respectively) that truly grounds the out-of-this-world series. Watching them pull from impressive depths and deliver consistent performances compensates for the slower and confusing plot lines in the show. Tune in for the dazzling mystery below their shed, the titular night sky that reveals evolving puzzles, but stay for the performances—grounded, honest, and ever-so gripping.
